Oscar 

1.A Russian asshole that loves to ruin your day after it has started out going well and thinks he is a fucking communist. He often needs to be reminded that WE ARE IN THE FUCKING UNITED STATES OF AMERICA!!!

2.A way of murder which often consists of a frying pan,a large array of screwdrivers,three rakes,9 feet of rope,6 feet of barbwire,a bucket and a rusty butter knife.

1. Alex,stop being such an Oscar.

2. Alex should shut the fuck up or I will Oscar him.

Oscar The Grouch 

When a girl passes out at a party, and she is dropped in to a garbage can. Before she wakes up, members of the party urinate and ejaculate on her.

Yo last night at John's house, they fuckin grouched some freshman!

We roofied that slut you liked and gave her the Oscar the Grouch. Sorry man

Oscar the Grouch 

This is for the chick that's willing to suck you off but lacks the skill and/or confidence to do so without making a mess. She sits down with a small trash can between her feet as you stand across from her so that said trash can will catch any spillage or the whole load, whichever she feels comfortable with. Its basically a training excercise for the future swallowers of the world. ^_^

o'girl really wanted a protien shake but did NOT want any jizz to wind up on her dad's new carpet so I recommended the no worries 'oscar the grouch' method.

oscartron 

Refers to any chemical, substance, or item that is volatile, unpleasant, and of only moderate use. Characteristically foul-smelling, and useful for one very distinct purpose that generally doesn't outweigh it's downsides.

Oscartron stems from a b-grade porn star who was good at a one particular act, but tended to alienate co-stars with poor hygeine and a volatile temper.

Those new sodium-cooled nuclear reactors are a total oscartron!

Oscar Party 

A euphanism used to describe an event in which mature couples engage in sexual intercourse.
Sometimes used to mislead younger people into the comforting belief that they do not have sex.

My father must really be hitting it off with his girlfriend. She's invited him over to her house for an "Oscar Party".
