It can be something said after a "your mom" joke, but that doesn't mean it isn't true.
And it hurts more when your friend thinks that your just trying to make a comeback, and keeps going...
Jeff: Does your mom want her underwear washed with bleach or without?
Carl: My mom is dead.
Jeff: Should I wash the body, too?
Carl: *beats the shit out of Jeff*

Something used after a yo mama joke, not only to make them feel like crap, but also to ruin everyones fun.
Joe-Yo mama is so poor, she goes to Kentucky fry chicken's to lick other people's fingers.
Chris-My mom is dead...
Joe-*looks sadly at Chris*

It is the most common comeback against a Yo Mama joke. Used in an emergency when one can't think of anything to say. Using it automatically results in Fail for being such a lulzkiller. Please note that this is NOT the ultimate comeback
Bob: Btw, can you get my wallet for me? I left it on your mom's dresser.
Drew: My mom is dead
Bob: That explains why she wasn't screaming so much

A response to the phrase "your mom", where the user is trying to make the "jokester" feel badly.
The jokester either apologizes or comes back with something witty.
Person 1: hey yo! Who's the man?!
"Jokester": your mom!
Person 1: dude, my moms dead okay...
"Jokester": oh my god, look I'm sorry, I didn't know...
Person 1: haha, look who just got pwned.
Person 1: You're gay.
"Jokester": your mom's gay!
Person 1: ... my mom's dead...
"Jokester": yea, I know... she's the reason I'm necro...

Person A: Hey dude, sup?
Person B: YOUR MOM IS UP!
Person A: Dude, that's not funny, my mom's dead.
Person B now either believes you, is confused/apologetic, or smart enough to prove the ultimate response to this; Yeah? I really like that.
