Snowbird

Qrowin is the Het ship between Qrow Branwen and Winter Schnee from the RWBY fandom.

Canon
Qrow and Winter both make their first appearances in the show in Volume 3. Qrow's dislike of Atlas, Winter's birthplace, is brazen enough for him to immediately get into a brawl with Winter upon encountering her and personal enough for him to back down at the last second just for the chance to humiliate Winter in front of her superior, James Ironwood. He also shows a level of cockiness when he baits Winter into attacking him. Winter, although lady-like and dignified, loses her restraint when provoked by Qrow.

Fanon
In RWBY Chibi, the non-canon comedic spin-off of RWBY, Qrow and Winter have a lot of moments together. In Season 3, Episode 3 - Mortal Frenemies, Qrow amuses himself at the expense of Winter over petty squabbles. Professor Ozpin reminds her that the two are on the same side, so Winter proposes a truce, which does not last long. As they continue to fight, Ozpin remarks that "flirting was a lot less destructive" back in his day.
