<human>: Can you condense the text into three sentences or less?

It was actually last week. None the less this senior in my math class passed his yearbook around and we all signed it. I signed last and wrote "have a good summer. shout out to Mia Malkova (NSFW) - dannykim15218". Back story, a long time ago i over heard his conversation and he was talking about pornstars so I turned around and asked if he knew Mia Malkova and he was like ayyy and that was our inside joke. so he gets the yearbook back and is reading it then bursts out laughing. the entire class looks at him and he yells "DANNYKIM15218 DID YOU SAY SHOUTOUT TO MIA MALKOVA?!?" the whole class pretty much thinks I'm a pervert.
<bot>: signed "shout out to Mia Malkova (NSFW)" in a yearbook and the kid read it out loud to the whole class.
