Frock

"'Hey there friend you're a real cool guy '""'You're the Honeycrisp apple of my eye'" Frock is the slash ship between Master Frown and Brock from the Unikitty fandom.

Canon
Master Frown is quick to see Brock as a "loyal henchman" for his evil schemes. This is most evident in "Stuck Together', where he is irritated with him offering cookies to Unikitty. He also has a tendency to demand Brock around, forcing him to come to the Doom Lords meeting, while also showing annoyance at him for bringing juice boxes to the meeting. However, deep down, Master Frown actually cares about Brock, such as in "Best Best Friends" when he apologizes to Brock with the latter's favorite song, keeping the lollipop Brock had gifted him at his birthday as a child as shown in "Trapped In The Tower", or in "The Birthday to End All Birthdays" when he hugs Brock with affection, but usually he is just to shy to show his true feelings for Brock.

Brock is more easygoing with Master Frown, treating them as friends rather than an evil duo. Despite this, he gets somewhat irritated at Master Frown's demands, as seen in "Stuck Together". When Master Frown yells for him, Brock is annoyed by this, since it was not necessary. He also likes to poke fun at his roommate, such as joking that his boss was angry at him because he forgets to do the dishes.

In the show, Master Frown and Brock share an apartment in Frowntown. The two often act like an old married couple. Since they were childhood friends, they know a lot about each other and Master Frown and Brock is shown to be really comfortable with each other. They have their own differences, but that doesn't stop themselves from having a good relationship.

In Episode 18, Best Best Friends, the two had sang a song about how much they love each other called 'we're the very best friends'.

In the final episode of Unikitty!, Brock was seen hugging Master Frown, much to Master Frown's delight. Brock then had kissed him.

Fanon
The shipping possibly first began when fans notice their cute interactions. The fans really liked their dynamic, Master Frown as the wild, chaotic, outgoing one, and Brock being the domestic, nice, housewife™. Fans has a quick eye on seeing their relationship becoming more as a couple instead of being just friends because c'mon now, just look at them. A lot of fans speculate that they are married for a long while now and it's the reason they've been living together.
