The dumbest way to shoot some one. What someone does when they don't have the balls to stick the gun in someone's face.
Grow some balls and stick the gun in their face Dave, don't pussy out and do a drive by.

Get a drive by mug for your cat Zora.
Before giving a female oral sex, start fingering her first, only for a second or two. Try to distract her somehow, kiss her ear or neck, and sniff your fingers to see if she stinks so you can decide if going down on her is worth it.
I gave that chick a drive by and damn that bitch stank!

What happens when chimps excape from the zoo and get hold of guns and motor vehicles.

Where Mv = Motor Vehicle, Ch = Chimp, D = Drive by. It can be equated as follows:

Mv + Ch = D

Where MD = Multiple drive by, and x is equal to any number greater than 1, the following equation holds true:

Mv + (x)Ch = MD
Hey look, those chimps have a gun and car keys! WATCH OUT!
