to insert only one's testicles and scrotum into a woman's vagina during foreplay.
"things were getting heated, but i didn't really even like the girl anyway. so when she thought i was trying to get it in, i was actually little nemo-ing her. she looked down, and even though she felt something, she saw my flaccid penis laying on her hips. it was hilarious"
