Balkan meaning of "I fuck your mom" It can also be used by ur mom, which is ironic, but yeah. It is used when u are so mad that you cant put your anger in words, so you say "JEBEM TI MATER!!"
Son: Mom I got an F! :(
Mom: JEBEM TI MATER! *chases him with papuca*
"Jebem ti mater" is a sentence by which a Balkan mother expresses her love for a child. When Balkan moms are angry, they run around the houseafter the child with a slap in the hand and shout: "JEBEM TI MATER!" Even tho that means "fuck you motherfucker" she uses it anyway.
