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!!!"

Merection 

Japanese dirty word combining the word 目 meaning eye , pronounced Me and the word erection.

Signifies a person who is looking at someone too insistently in a creepy way

I went on a date with that guy but his merection was way too obvious, it was scary.

Merection 

When you give yourself an erection, with no help, no porn just all by yourself.

I looked in the mirror and gave myself a merection...
