kneebang

is the act of inserting one's penis into the "kneeslit" of another person's leg, and going in and out. The kneeslit is a slit between the thigh and the calf, which is formed when the knee is bent all the way, forming a makeshift vagina. Also known as kneesex.

Kneebagged
(Adv.) like tea-bagging, but walking up to a relaxing person - in a reclining position - and just dropping your nuts on their knee, unsuspecting.

Yo bro, look over there!
(Nut drop on knee)
WTF man! I can’t believe you kneebagged me again!
