look up any word, like bukkake:
 
1.
When a guy overshakes after urinating.
Joe found himself in a predicament after he went spazdick and splattered his neighbor in the mens room at the Yankees game.

2.
when a penis slaps its owner several times while he is sleeping until he wakes up to notice he has ejaculated.
HER: Your a real spazdick!
HIM: I swear only sometimes, if we had sex, it wouldn;t happen!!!!
