Get the Billymug. The term Billy can be used to describe someone who keeps on flexing, even when he doesn't mean to. It can also be used as a tier 4 insult to basically anyone

Get the Billymug. A man with an incredibly small penis, he never quite hit puberty, but he still likes to act as if he has a big dick. He insults others to make himself feel better, and more unstable than Lindsey Lohan on a drug kick. He doesn't realize that his friends don't even like him anymore, and he watches more gay porn than Justin Bieber. He still pretends that he has an interest in woman, but in reality, he looks at fantasizes about other men's schlongs, wishing that one day, his could be that big. He masturbates so often, everyone is curious as to how he would, his hands would strangle that tiny thing! He never really hit puberty, so he has almost no body hair.
