Science made up by a bunch of meatheads in a trashy, piece of shit gym in a basement.

2: shut the fuck up you meat head.

2: you just made up that meathead science.

Meathead moment 

1. To perform an action that others would consider unwise or illogical.

i.e. I had a meathead moment when I ran that red light and got pulled over by that cop.

Meathead Moo-Hard 

A large, boisterous, round, angry, impoverished degenerate purchasing meat products with food stamps at a truck stop while under the influence of drugs or alcohol.

I wanted to spice up my nachos but some meathead moo-hard snatched up all the onions from the condiment bar.

Hamilton Meathead 

The kind of guy that is super proud to be a "grill master". Owns every kind of grill known to mankind, knows every cut of meat and what it is best for what. Posts pictures of grilled meat all over Instagram. However, the meathead also likes to drink while grilling and doesn't notice his expensive grill is on fire.

Look at Ryan, that Hamilton Meathead hasn't noticed his Traeger is in flames!

Should we tell him?
Nah!
