look up any word, like pussy:
 
1.
An eroticism whereby your girlfriend screams your best mate's name instead of yours during intercourse. This eroticism evolved after a man called Simon wanted his wife to cheat without actually cheating. He asked her to scream "Matthew" to satisfy his desire without the heartbreak.
Mostly exclamations such as, "Oh Matthew!" but/or possibly "Oh Simon/Boyfriend, Matthew does!"

I was Matthewed last night.
