How can I make it up to him..?

Last night I was playing a board game with my boyfriend and he did something bad in the game that made me mad. I better preface this by saying we are an extremely jokey couple and are constantly making fun of each other, messing around, playing pranks, etc.

I was trying to say "go fuck yourself" or "I'm going to kill you" or "kill me" but I accidentally jumbled them and said "go kill yourself." Yeah... love my brain.

He got so upset and didn't believe that I accidentally jumbled the sentences and wouldn't speak to me for the rest of the night or tell me he loved me before bed or anything...

How can I possibly make this up to him..? He is so beyond upset and I cried so hard trying to get him to talk to me bc I absolutely did NOT mean to say that and never ever would...
