Your Mom Says Hi

Get the Your Mom Says Hi mug.
Line from "Back to the Future" 1985, Universal delivered by Biff to Marty McFly after Biff has wrecked the McFly family car, had it towed back to the McFly residence and denied responsibility for it.

Biff desired Marty's mother when he, Marty's mother (Lorraine) and Marty's father (George) all attended high school together and Lorraine choose George opposed to Biff.

Biff is still stinging from it some thirty years later and has no problem taunting Marty with an inappropriate and disrespectful comment that he still desires Marty's mother, a married woman.

Get the Say Hi To Your Mom For Me mug.
An expression used after a coffin-nailing slam, coined from the oft-used phrase by characters played by Marky Mark Wahlberg, and lampooned by Andy Samberg on Saturday Night Live.
Person A: Your mamma's so fat, when she (blah blah blah), etc.

(Person B stares aghast, unable to speak, at the slam that was just delivered to him.)

Person A: and say hi to your mother for me
-----
Or, after a physical altercation, the victor spits on the loser, and proclaims with disdain: "say hi to your mother for me".

Get the say hi to your mother for me mug.
A phrase implying that the person saying it "knows" your mother, but in the biblical sense; and that your mother is a woman of easy virtue. Interpretation depends on the context, of course. In the long tradition of putting down someone else's mother as a way of putting them down. Alternatively, just "say hi to your Mom."

You've heard the chant right? What it sounds like you're insinuating is that they're supposed to be chanting MY name.
Hym "Is that a thing? When they're chanting the 'Say his/her name!' shit it's supposed to be 'IAM HYM! IAM HYM!'? That would have been dope. I feel a little robbed though... I feel robbed out of my minions... I wanted to wield them against my foes. Instead some retard is making them paint streets and tip cop cars. He's wasting perfectly good minions. And some of them are hot so I could be fucking the hot minions. This whole thing has been a wash. *Sigh*"

what rove mcmanus (an overrated talk show host in australia with lame jokes) says at the end of every show of 'rove live', which by the way has some very cool and funny guests.
