A term for above averagelarge breasts. Band sizes larger than 36 and Cup sizes well past F (DDD). Usually cannot buy bras from traditional stores and must custom order or have imported. Cup sizes can range from G to O usually.
You see I’m a 40L, I have a very uncommon bra size. I can’t just send my Mack Truck Mamories out to every guy who smiles at me...
Unlike throwing a hotdog down a hallway which means u banged a really loose chick, "Like Trying to Drive A Mack Truck Down a Hallway" means that u had penetration problems or she was just really tight
For example my cousin was unable to bang his girlfriend because she was to tite so that situation would be described as Like Trying to Drive A Mack Truck Down a Hallway
