A Sushi Toothbrush is where you are woken up by someone who has recently fingered a woman sticking their index finger in your mouth and brushing your teeth like a toothbrush.
Often performed on the morning after a party or by a moody wife thinking of different ways to get her husband out of bed.
Most effective when used on someone who has never eaten muff before.
(the night after a party)
Man: Is Jason still sleeping?
Woman: Yes, he's asleep upstairs, why?
Man: Well I just fingered a girl and I'm pretty sure this is going to be the best chance in my life I get to effectively Sushi Toothbrush someone.
Woman: You do know I'm Jason's mother, right?
Man: .... Your point is?
