ur mum

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"
