The Marcellus Erectus is a sexual act, where the male is going to pound town doggy style and screams "Do a kickflip" as he reaches climax, flips the female over onto her back, slaps her in the face with a bratwurst, then immediately grabs her ankles to roll her off the bed in a reverse somersault into nearby furniture.

A dirty ass dog who will cheat on you for some raggedy ass bitch. A man who is manipulative and a compulsive liar and has no feelings. A man who will sit and play “stepdaddy” and raise his ugly ass bastard children.

Someone who is amazing and very caring about other people's feelings. Always full of happiness, joy and love. He's not afraid to speak what's on his mind. And has an annoying big brother named Tre.
I love you Taylor! - Marcellus
