5.0 

In 1982, Ford reintroduced a high-performance Mustang GT which opened the door for an entirely new era of the muscle car. Wringing a then-respectable 157 hp from its "5.0" (actually 4.94 L, 302 in³) Windsor V8.

The "5.0" Mustangs, cars that gave birth to an entire aftermarket performance industry, continue to remain extremely popular today.

Pronounced "five point oh."

5.0 Coyote

Engine in 2011 and up mustang gt. Put a 2.3 TVS blower on it and its faster than Bill's ZL1.

Even with a built ls3, ported heads, blower, full exhaust, tune, and 75 shot, Bills ZL1 couldn't fend off non liberal's 2013 5.0 Coyote Mustang.

2.5-0

A security guard. Derived from 5-0, slang term for a cop. Security guards carry about half the credibility and authority as a regular cop, hence the 2.5.

See also rent-a-cop, mall security.

"Bobby and I were throwing mustard off of the balcony, then some 2.5-0 come by and threatens to calls the cops. Lame"

Tosh.0 Douche 

That guy who always walks up to you and your friends and asks "Did you guys watch Tosh.0 last night hardy-har-har" or "Did you see (insert part here) last night", when you are the one who told him about the show in the first place. You probably did watch the episode and therefore are not in the mood to listen to the douche's play-by-play of the whole episode

Me: Yeah I'll be at home tomorrow, why?

Friend: We can hang out.

Tosh.0 Douche: *walks over* Hey guys did you see when Daniel Tosh called that mexican poor and uneducated?

Me: *sigh* Yeah... it was kind of funny....
