Dude, I went into your mother's cavernous vagina the other day and found these awesome pants!

Mother's Basement 

An insult used by hypocrites who live in their mother's basements.

"You are an idiot. Your 20's weren't raped by anybody in this administration. The fact that you sit in your mother's basement writing blogs and bitching about the state of afairs, while in reality doing nothing is laughable. The fact the people put stock in your opinions is sad. This movie is going to bomb, because people see O. Stone for the moron he is."

Mother's Milk 

Fourth full length album of the Red Hot Chili Peppers. Following the death of former guitarist Hillel Slovak, the album marks the debut of guitarist John Frusciante and drummer Chad Smith. Known for being the start of the groups commercial success, it features a variety of songs ranging from the funk laden riffs of "Subway to Venus" to the firey goodness that is "Punk Rock Classic".

There isn't a bad song on Mother's Milk.

Mother's custard

Milk from one's mother's breasts, and more importantly a desire to drink that milk from her breasts.

When Jack got a whiff of lactating nipples in his house, he just knew he'd soon be enjoying a drop of Mother's Custard.

but the point of the story is, your mother's a whore 

1.When you are telling a story and have engaged a listener but realize that the climax of the story is not nearly as enthralling as the build up, this phrase is used to complete your story with an unexpected slam on the listener instead of trailing it off at the end and disappointing yourself and your audience.

2. Alternative ending to a "and then I found five dollars" type of story.

"Today I got to work a little late and there were rumors about my company letting some people go. This afternoon, my boss called me into his office and sat me down across from him with a solemn look on his face... and well, he didn't fire me, but the point of the story is, your mother's a whore."

Your mother's mother's face

The next level in the progression of the "your mother" insults, after "your mother's mother" or "your mother's face". Should be used in the same meaningless fashion as "your mother", perhaps when you've run out of insults, or need a step up from the lame "your mother" insult already directed at you.

Person 1: What up
Person 2: Your mother
Person 1: Yeah well your mother's mother
Person 2: OHHH well your mother's mother's FACE!
Person 3: BURN!! He's got you there...
