its when you cum 3 times on a girl's back, then you dip your NUTS in the cum. After that you put your whole nut sack into the girl's vagina. Last but not least the girl sucks your nuts clean so she can taste the cum and her own juices.
You: Hey Jennifer, I'm bored can I give you a dirty squirel.

Jennifer: Sure why not!
