A variation of the "Mother Insult" type of joke/taunt. My friends and I use this as playful banter.
Person A: Hey, your mom called.
Person B: Yeah?
Person A: Yeah, she wants to know if she can borrow some batteries for her vibrator. (Or something equally disturbing)
originally derived from "your mom" but suffixing the "called" after a brief pause to add comedy and confussion to the recipiant
person a: dude, you're dumb
person b: oh yeah... well... your mom!... called.
person a: (confused) seriously?
(November 20th)- On this day you have now have permisson, by me, to (call your teacher mom)!
(Student) - "Hey, Mom!"

(Teacher) - "Im sorry, I must have been mistaken! No detention today!"
it is a way to trick your friends...

You: yeah your mom called she said your butt smells!!
When you lose every chance at getting laid because your mom calls with enough guilt and religious talk to kill your boner for a month.
