Keico

Keico is the slash ship between Boyfriend and Pico from the Friday Night Funkin' and Pico's School fandoms.

Friday Night Funkin'
Pico was hired by Daddy Dearest to kill Boyfriend after he was embarrassed by him in a rap battle in Week 1, but Pico didn't know he was employed to kill Boyfriend. He ends up sparing Boyfriend's life and only rap battling him because he was "somebody he once knew".

In Week 5, Pico can be seen in the background spectating during Boyfriend's rap battles with Daddy Dearest and Mommy Mearest.

In Week 7, during the cutscene for Stress, Tankman tells the other Tankmen to kill Boyfriend and Girlfriend. Before they fire, Pico hops down onto the speaker and kills some of the Tankmen. Pico continues to shoot other Tankmen on the speaker while Boyfriend and Girlfriend rap battle against Tankman.

On April Fools, Pico's School was updated to have Pico deal with Cassandra in a less violent way. In the end, Cassandra reveals that on her planet, everyone is gay, and that they know that people on earth are homophobic. Pico responds to her by saying that not everyone is homophobic. He proves his point by showing her his boyfriend, Boyfriend, and claiming that everyone in his school accepts them.

Pico's School: Love Conquers All
The game reveals that Boyfriend and Pico had been dating when they were teenagers and went to the same school.

Fanon
The ship started off with fan theories regarding Pico and Boyfriend's relationship. Many people guessed that they had previously dated, and some even believed that they were currently dating. Once these theories became increasingly popular, Tom Fulp and Ninjamuffin99 made joking tweets about how Boyfrico was canon. However, Ninjamuffin later changed his mind and decided that it was no longer a joke.

Although it is confirmed that they are exes and that even Boyfriend has a girlfriend, the fandom still likes to ship them in love triangles with other characters or even believe that they are in a polyamorous relationship with Girlfriend. which has led the fandom to create their own mods about their relationship where they are still boyfriends. The most popular mod in which they are still a couple is called "Soft Mod". Boyfrico is arguably one of the most popular ships among fans. Keico is the most popular ship in the Friday Night Funkin' fandom on AO3. It also caused a resurgence in Pico's School content, causing Keico fics to overshadow ships between characters who actually originated in Pico's games. Despite its popularity, some still believe that relationship status is just a joke and prefer to ship Boyfriend with his current partner, Girlfriend. Additionally, even if people believe they are exes, another large percentage of the community does not like Boyfrico, and ships Boyfriend with Girlfriend or Pico with Nene instead.

Trivia

 * Ninja_Muffin99 (FNF's Creator) confirmed in a tweet that they were canonically boyfriends, now ex in the game timeline. The fandom believed that it was all a joke by part of the game creator himself, but it was later confirmed by the creator of Pico (Tom Fulp).
 * Boyfriend and Pico are both canonically bisexual.
 * The ship name derives from "Keith" being one of the Fanon names for Boyfriend. Even though the theory (among others) has been debunked in the game itself, people continue to refer to the ship as such, for the lack of a better name.
