Bakugou gives rude yet suiting nicknames, it's common knowledge because everyone gets one from him, what people typically don't notice, is that you do the same, well, with more subtle nicknames half the time, so usually no one noticed or they blindly thought it was cute, yours all depended on how you liked someone when you first met them and gave them the label, many of your class members were used to nicknames because of Bakugou, yours weren't as bad so they were let slide, Bakugou found it quite funny to be completely fair, so at some point- Bakugou sat beside you in the next Bakusquad hangout

"What do ya call them again? I need more creativity in some of mine, I'll admit" Bakugou says with a hint of a smirk, this is a peace offering
