mackload 

A very large amount of something; mackload takes its meaning from Mack construction vehicles, which are capable of hauling very large loads.

I ate a mackload of mint chocolate chip ice cream and now I feel sick.

Muckload 

Giving your slut a mouthfull of seamen and sperm.

Muckload. A load of jizz. A load of muck.

mackladon 

A large carnivorous dinosaur-like char propelled by membranous paddlelike organs attached to various parts of its body. Most frequently found in deep, cold bodies of water adjacent to schools of inconsequential silvery food fish.

When Johhny started talking smack, I juiced my bait with pro cure and lowered it down to 42 feet where an 11-pound lake trout grabbed on the first pass and while I was reeling it in, a mackladon tried to eat it.
