When anything contains a high dose of Chevy Chase and is therefore hilariously awesome.

Chevy Chase does not actually have to be physically present, as long as his spirit is embodied.

Heavy Chevy = good
Straight Lampooning = good
No more Chevy = lame (a.k.a. Friends or America's Funniest Home Videos after Bob Saget left the show)
Did you see Dale* trying to learn to ride a bike? It was Heavy Chevy!

*a 22-year-old noob with cheese stains on his crotch who still doesn't know how to ride a bike

Contrary to the other definitions, the term heavy chevy was originally used by General Motors as a trim package on the early 70's Chevrolet Chevelle's aimed at people who wanted muscle car looks for relatively low costs and lower insuarance rates.

A low level Chevelle that was produced from 1971-1972, it had all the power of the SS but was cheaper and look basic on the inside but it had stripes on the side.
Bill couldn't afford the Chevelle SS so he bought the Heavy Chevy instead.
