A hot mama; a hot babe; a ho of particularly hispanic/spanish but possibly other decent

It simply means "hottie" in Latin-American slang.

"Mamasita" is a misspelling of mamacita, the Spanish for "little mother". Rather like the English word "momma", mamacita can mean a mother of both the standard and the red hot kind.

Fuckable Latina

When you see a hot girl, is like saying lil mama
