Jack Blade quote from Tropic Thunder. His character was experiencing withdrawl from cocaine and he was tied to a tree. Crazy shit ensued.

Basically, It means your mother sleeps with everyone and has deseases between her legs, and most likely, you are unwanted crotchspawn.
"Your mother is a cankerous whore!"
"Damn."
"Hey, remember that time I called your mother a cankerous whore? I didn't mean it man, she's a nice lady." - Tropic Thunder

This expression probably originated from the Hebrew expression "swear in your mother!" which is used as an exclamation conveying disbelief or surprise.

Your brother your mother

Possibly the most dangerous phrase since humans have developed vocal cords, above “your sister a mister” and “ your granny tranny”. Every time this is said the universe speeds up, the sun expands and god himself worries for his future
person 1 your mum gay
person 2 your dad lesbian
person 1 your granny tranny
person 2 your sister a mister
Person 1 your brother your mother
god *cries*
