You were cooking while bakugou was playing Call of duty with Kirishima and todoroki was watching them. Deku came up to you not paying attention but he was gonna show you something on his phone.

Deku:"Hey mom-" he paused once he said mom. You whipped ur head around in shock to look at him. You even paused cooking..

Bakugou and Kirishima:"HAH- DID HE JUST CALL HER MOM??"

todoroki:"Oh wow."

Deku:"NO I MEANT-!!"
