well duh it is ur mum what else were you expecting.
Timmy: can you come to my house after school?
you : no
timmy : why
you: UR MUM
the mysterious figur who will come and beat you up if you shit in the sink at exactly 4:20am when you shout among us at the top of your lungs 69 times- she will also end up skimming your family.
What are you doing later?
Ur Mum.
IS IT JUST ME OR IS YOUR MUM LOOKING KINDA THICCCCC
when someone has nothing to say to a sentence, they say the phrase "ur mum" or a "ur mum" joke since they cant think of anything else with their nincompoop brain.
"Ugh i wish you would listen to me, even my mom listens better" "probably because ur mums so fat and her ears are so big even when shes tired of your bullshit she still has to"
ur mum is pretty much ur mum aka also known as ur mother and ur mum is a very common occurrence in a conversation with your friend
if u were talking u say "hello my g ur mum looks leng"
an insult that is so painful to the opponent that most of the time he just dies
Jeff: your birthday was good
Sam: ur mum was good
Jeff: *dies*
