Gainussing 

To insert the barrel of a firearm into one's anus in an attempt to expand the anus for introduction of foreign objects.

My girlfriend is gainussing so that we can try putting a bowling ball in her anus.

Gavinus 

Is a man with a heart. Long for Gavin and originating from Sir Gawain one of King Arthur's knight's. Gavinus is a great friend and most Gavins have leadership personalities.

Gavinus facts:
Supportive of anyone, will do anything for his friends, great at the Sword and Fist arts, marksman, big cock-er-spaniel,
Incredibly loving to all, but carries grudges for enemies.
Gavinus has his flaws however,

Most Gavins suffer from health problems but push through strong, has a strong mind and is not fooled, (this can be a flaw because it can make it near impossible to prank him) and cannot be scared. Only scared of losing his loved ones, Gavinus doesn't fear like most. He charges into threats for a fight even if it means to the death. I fought a Gavin once and these peaceful creatures hit like a freight train and ALWAYS get back up unless dead. Befriend a Gavinus/Gavin.

Tip: the deeper the voice of Gavinus, the more loyal. If he talks in a higher voice to you he likes you, but in a fight... His crys for blood thunder throughout the skies.

Steven: "Have you seen Gavinus?! He's so awesome he stood up for us against Terrence at school!"

Lawrence: "Damn he sounds like the real knight Gawain!!"

Gavinus: "Who does? Hahaha let's go get a drink my friends!"
