Suck on my Camelbak Bitch!

Similar to the female "cameltoe," the camelbak is a protrusion of the male genitalia through excessively tight or highly pulled up pants. The resulting bulge resembles that of a camel's back.
It was clear to me that Louis was double ballin on the left side, as I could clearly see a camelbak through his tight leather pants.

A Back Pack you wear that holds a bunch of liquid. (Most of the time liquor) You then suck it out of the back pack with a straw or tube. I believe there may be a better word for this, but I have heard CamelBak used many times.
