A sexual position in which the male bends over and sticks his dick backwards between his legs and the girl backs up onto his dick while making beeping noises like a Mack Truck. Variations include the Wide Load (women in excess of 200 lbs.)
Guy: Yo my girlfriend pulled the Mack Truck yesterday. I nutted everywhere
Other Guy: Dude thats so ballin. Did you try the Alaskan pipeline after?
Guy: No I've been constipated for weeks so I didn't have any frozen shits laying around

Heavy flirting, pulling out the stops for that head-on hit-on.
Macking like your life depended on it.

Dude, she's my soulmate; I was mackin' her like a truck.
But she passed ya like a Mazda.
I know, who can resist my rollin' mack truck?

The huge space between a human's two front teeth that clearly indicates braces were necessary but not entertained. Now because of the zero igknowledgement to the issue to appears like you can drive a mack truck through the space. Although not reservered for poor white trash - it usually rears it's ugly head in that neck of the woods.
