When a person, usually a douche bag, gets excited because a girl that he is hooking up with is bringing "Mamis" out to the club with her. So he then brings it upon himself to do a stupid dance in celebration.
"Hey yall guess what (insert Spanish girl name here) is coming! and shes bringing MAMI'S!!!!" (does the "Mami Dance" when yelling MAMI'S)
