Overspeed 

To indulge in too many alcoholic beverages to the point you can't control your actions. Overspeed is when the most amount of alcohol your body can handle safely is overstepped.

I went out for a few beers with mates and I oversped to the point I don't know how I got home. An engine overspeeds when it goes faster (harder) than its capable of. smasheddestroyedruineddrunk as bro

overbreeder 

People who can't stop having kids and think that having tons of kids is fabulous, AND who think people who have just one child are horrible people for raising "spoiled", "selfish", "socially maladjusted", "lonely" only children (ridiculous stereotype myths in quotation marks). Overbreeders are usually putting those negative stereotypes on well-behaved, well-mannered, calm, happy only children at the same time as they're losing their minds running around in a tizzy trying to rein in their completely out-of-control, fighting hoard of kids.

The overbreeder Duggar family from Arkansas has 16 kids and wants more - scary!

Oversteer 

Occurs when a car has exceeded it's limit of grip. The back end kicks out, resulting in either a powerslide or a complete spinout- depending on the driver. Oversteer is the basis for all drifting, and when harnessed can look amazing.

-Oversteer is deeply statifying when controlled- it is the ultimate show of car control!

-JC may be a better presenter, but Tiff Needel sure can powerslide!!

-The onset of snow often causes many people to experiment and experience oversteer, some intentionly, some, accidently.

Oversheened 

The feeling that Charlie Sheen is making sense that one gets from being exposed to way too many Charlie Sheen quotes.

I watched that whole Charlie Sheen interview and now I'm totally oversheened.
