One who speaks highly of their penis when in fact they have very little penis to speak of.

someone who is sexy beyond mean

A person (male or female) who won't stop building themselves up. To inflate their ego so high, people around can't help but get a pin.

someone who conversates in a way where they think they're right and you can't persuade them as if they're holding a gun to your head (cock as cocked gun and a penis cause they're incorrect and they wont accept that they are)
