Any car, whether actually resembling a limousine or not, that is inherently lame, has lame people inside of it, is housing any sorts of lame activities, or has any other applicable reason to be construed as lame. These cars are often driven by wiggers, Chads, etc., but can be driven by any normal person as well as long as there is any vague reason to call it lame. Most often, these cars are made even more lame by tacky accessories added in poor taste.
Dude, did you see that crappy 1996 Buick that just drove by with the fake chrome and spinning rims and totally unnecessary sound system that's probably worth more than the piece of shit bucket of bolts that it got crammed into? What a fucking lameosine!
