Your mother's onion

Something you say to a person , to which you are speaking. It means your mother has fat thighs and vagina, therefore everything it that vicinity gets squished together. Creating a vagina/thigh area that looks like an onion would if you cut out a small slice from one side.

Good example: Your mother's onion was a nice ride last night.

Bad example: Your mother used her onion to make fajitas last night.
