Mantastic Number

A song in a musical in which the singers are all male and the song is of a high manful quality; usually involves singing about objectifying women and/or fighting.

The song "Dames" from the Musical "42nd Street" is my favorite mantastic number.

mantastic 

Feeling fantastic after the successful completion of a particularly macho feat.

Following his fifth keg of beer, Kevin ripped the horn off of his pet narwhal, and then nailed his porn-star girlfriend for hours. Subsequently, he felt mantastic.

McSpastic

An employee at McDonalds that either:

A: Gets your order wrong, regardless of if you check it with them or not.
B: Creates a McDonalds burger that either looks like it's been used in a food fight or a spastic has put it together.

"Some fucking McSpastic got my order wrong!"
"Which fucking McSpastic put this piece of shit together?"

mastasia 

Having absolutely humongous titties. When you think humungous, think even bigger than that. Poor girls will have back problems all of life, carrying around titties that weigh more than the rest of their bodies.

I like big boobies, but mastasia is way way too much!

Mantastic 

someone or something that is overly manly but not egotistic, and is just alittle bit cooler then being fantastic.

The fact that the fat guy could lift a 2 ton car was mantastic.
