using buddy 

"Using buddy" is a term used to describe an addict's primary partner in crime who is at the same level of addiction and decision making as the addict themself.

Using buddy can be a compliment among addicts "you are the best using buddy ever!", or a disparaging comment - for example if someone calls you a crack addict in a critical way because of your behavior, and you reply "fuck you, using buddy" to indicate they are the pot callint the kettle black.

Using Mathematical Equations to find out why the chicken crossed the road 

1. (Idiom) Using a very complicated method or strategy when there is a simpler route that ends up with the same conclusion.

2. (Noun) A scientist in an insane asylum writing on the walls trying out figure out why the chicken crossed the road.

3. A question that has puzzled man for a very long time.

Ex:Using Mathematical Equations to find out why the chicken crossed the road

Lets see... The road is the variable y. x is the chicken...and w is the width of the road. Was the chicken hit by a car? Lets set that as variable q.

-46 Years Later-

Heh heh heh... So close to finishing!!! The chicken... crossed the road...because...

x=324897.453710599487105720982/23857105.3234 X 5^3489.245783-2433.452359157837598283994750175

y=45732658935/435 X 6^6.345722

w=2350701957303958.23095

q=23688.7853574545/534365645 X 235798^4364534577.3

He..he crossed the road... because...FFFUUUUUUUUCCCCCKKKKKK!!!!!!!!!!!

Who is THE Chicken? Who the fuck is he? Is he a fat chicken ? How fast was he going? (The scientist has now mentally gone insane)
