Back-Seat Stain

When a Sneakers O'Toole look-alike has a cab service from school to the club. Sneakers O'Toole then lets every chick in his car drink, and inevitably, they spill some cranberry/vodka on his seat. Sneaker O'Toole will get the drink stain confused with a Virginia Slim stain.
Sneakers: Yo man, I'm gonna have to run by the cleaning section. Someone spilled some shit in my car. Now I think I have the Back-Seat Stain

Grinnell: Actually, I think it may be a Virginia Slim stain.

Sneakers: You know... that may actually be what it is.

Sid: What the fuck!! Hahahahahahahahahahahahah!!!!

Unassigned Assigned Seat

A seat in class (most often a college class) that you normally sit in all the time; so much so that it practically belongs to you. More often than not, the majority (or even the entirety) of the class has one because they pretty much always sit in the same seating arrangement every class. However, if the seats are not officially assigned in class by the professor/teacher, someone else could sit in your unassigned assigned seat either without knowing that you normally sit there (perhaps they're new to class or just never noticed), or in rarer cases deliberately, causing you to have to find another seat with discomfort and awkwardness. You feel that you HAVE to sit there every time because that seat is yours.
Someone sat in my Unassigned Assigned Seat in class today, even though they knew I always sit there. I felt so stupid when I had to find another seat to sit in.

seat belt effect

Where the strap of the seat belt proceeds to split a woman's breasts, thus making them appear bigger and more noticable

Back Seat modding

When a person tries to act like a mod or an adminstratior of a forum. They are general pain in the ass, piss people off and so on.

They are supreme butt-kissin' suck ups.

Stop back seat modding!

No one likes a back seat moder.

Toilet seat necklace

T-S-N for short. The act of wearing a toilet seat around your neck, allowing the person shitting on you to be more comfortable whilst doing so...
1 Boss - "welcome to company, we are looking forward to working with you. If you go see Linda in HR she will issue you with your company T-S-N (toilet seat necklace), remember to wear at all times as we like to be comfortable when taking massive shits on you."

1 Employee - "thanks that sounds supes"

A first world injury can often occur when C.E.O's are forced to unload a massive steamer on said employee when not wearing their T-S-N

frisky toilet seat

A toilet seat that pinches your ass upon arising. Most common with wooden toilet seats that have an invisible hairline crack that opens with the weight of someone sitting but closes up and grabs some ass skin when the user rises and the weight is removed.
That frisky toilet seat at school got me for some skin and hair.
