when your banging a girl and you’re about to cum so you pull out and start clacking so it goes up in the air like snow then she tries to catch it in her mouth like snowflakes
A sticky snowball is when a guy catches his cum load in his hand and proceeds to throw it at his target, preferably the face of a cheating dirty whore.
Austin Wilson is such a cum craving homo that he begs all of his friends to cover him in warm sticky snowballs.
I found out my girlfriend was cheating on me so I surprised her with a barrage of sticky snowballs as a going away present.
