A chubby girl who is not so fat that she becomes completely sexually unattractive, but is too heavy to be seen socially with. A chubba may be in a lower social stratum and is never higher in status and is often seen as being uninteresting, uninteligent, and generally worthless. A chubba is often a single man's equivalent to a mistress, whom he maintains for sexual purposes whilst shopping around for a more decorative mate.
It's been two months since I've had any ass. I'd better call up my chubba in Riverside.

I'm showing up stag. It's not like I'm going to bring my chubba to a wedding.

I went to see my chubba last night. I felt bad about leaving without flushing her.
