A really lame comeback, for people who can't think of a decent one in time. Was very popular for a time, but now has died down. These comebacks are related to the "Yo Mama" jokes which are just as bad.
Person 1 - Go fuck yourself.
Person 2 - Ya mum...ummm...yeah! Ya mum fucks herself, hahaha wasn't that awesome guys, Burn Person 1!
A hilarious insult that me and my friends say constantly, people say that there is no come back but there is.
timmy-u stink
me-ya mum stinks
timmy-ya mums dad stinks
me-ya mums dads family stinks
timmy-ya mums dads familys face stinks
me-your mums dads familys faces mum stinks
and so on
where my dick lives
also where all my friends dicks live
'Dude, Where were you last night?'
'Ya Mum!'
