J-Slap
When a guy licks his hand and slaps a girl's snatch to make her wet and turn her on. It's gross, it's hot, and it's usually followed by a lot of laughing and a lot of embarrassment.
My brother j-slapped his crush in front of the whole class and she turned bright red.
He j-slapped his girlfriend in the middle of the grocery store and she laughed all the way home.
At the party, he j-slapped his friend’s sister and now she’s his new crush.
