" First time i got high when i was in my friends bathoom smoking a 10 bit with him, we smoked 5 bit first, "

Howdy..what's a 10 bit ? It sounds mighty powerful,to git y'all so messed up. I'm from Texas,USA and I don't reckon I've heard of '10 bits' before,back in the old days,American's used to refer to a 25 cent coin ,as "two bits".
