lol sure i was childish at 12. my mom passed away when i was almost 7, if anyone says something like that to me now i wouldnt act childish and hit him with a bat. he'd probably get his teeth knocked out the ol' fashioned way lol but like you said. people who get upset over simple "yo momma" jokes are too sensitive.
Well i would definetly get mad if the guy knew my mom was dead. But if it was just an honest joke and he had no idea I would cut him some slack. But I don't knwo for sure cause my mom's not dead. I know it probablly doesn't mean much, but sorry to hear that.
