it amy be because we are two diff people, but we are both grown men. if someone called me a pussy i would get mad and diss em back but no need to catch a fade. he didnt call you a bitch. pus is just an extreme version of the words scarry cat, punk, sucker, loser, et cetera.
given that you two are in battle mode right now, everything goes G. but if yall wasnt in battle mode, i would understand the fade. honestly reggie, you too grown to be trying to fight a nigga for callin you a pus. if you know you not one, enuff said.
