When a girl's ass is so big, it looks like she's driving around a dump truck.
Example 1:
Zack: Woah did you see Alexa today?

Chad: Yes! I saw that she is a CDL Holder.
Zack: Another one on the CDL list.

Example 2:
Zack: Excuse me miss, do you have a CDL license for that dump truck you drive around?
