The derogative name used to describe one who is so pussy that it would be generous to refer to them as a normal size pussy, hence baby puss. A baby puss often cannot complete a proper sized bong hit or drink a reasonable amount of alcohol. One can often identify a babypuss through a trail of gay beers or the lonely kid crying outside of the party because he is drunk.
Wow! Narus just poured out his third beer tonight! What a fucking BabyPuss!!

Hey BabyPuss clear the fucking bong. Textbook pussy
