2.
A word used by stupid 13 year old wannabe Mexican girls. There's no way to use this word with out sounding, stupid, bitchy, and Mexican.

If your a 13 year old girl who has an IQ lower then 50, and wants to sound like a Mexican, this word might just be for you.
Wanabe Mexican1: Eh homes! Yo mama es secca!

Wanabe Mexican2: No homes, Yo mama es secca!

Wanabe Mexican3: Hold up homes's, Me mama es secca!
