One of Rallo descent who calls (sees) every bet placed in a Texas Hold em poker game, no matter what cards he holds in his hand.

Get a Callo mug for your Facebook friend Sarah.
The gnarliest of gals willing to full send 24/7.

She's Cute, She's a toe, and she knows when she's a hoe.

Contrary to believe, she is quite brilliant in her own special way.
Also a low key bitch... but she's worth it - mostly.
Guy 1: Dude whose that girl?
Guy 2: That's Jess Callo; she's legit.
