I feel like we really get along well, but I can't commit to a relationship until we have sex. I'm a megasexual.

Megasequin 

An alternative unit of measurement wherein a sparkly glittery sequin, most likely found on a figure skater/hipster, can be used to describe distance or awesomeness.

The formula for conversion follows:

10^6 sequins = 1 megasequin

10^-6 sequins = 1 microsequin

*a sequin is one unit of fabulousness/length

Kim and Brent combine raw power with grace and artistry in a sport where success or failure is measured in microsequins.

Though 30,000,000 megasequins apart, you are still close to my heart!

The band was about 42 megasequins better than the opening act.

Megarection 

When a person becomes aroused, and their penis goes erect, and beyond hard. Swollen and massive, such an erection takes longer than average to go away, and can often cause uncomfortableness with the bearer. However, the Megarections should be worn proudly, in all situations, despite cultural or social norms

"So, last Friday I was struck by a huge boner in the middle of class...we're talking GIANT"

"Yeah, a Megarection. Get those all the time"

"What? I was so embarrassed!"

"Dude, rock that shit!! MEGARECTION!!!"
