gunhumper 

A hard-core gun enthusiast that always brings up the second ammendment to defend guns during mass gun killings. These people live, breathe, sleep with and hump their guns because they love them so much. The bigger the gun, the smaller the penis they have.

The ultra right wing of the Republicans and Tea Party crowd are the biggest gunhumpers of them all.

gumhummer 

The same thing as a gumjob or gummer. It's a hummer from someone without any teeth.

I met this 80 year old chick at the bar last night. She took me home and gave me a mean gumhummer!

Gumphumper 

Having sexual relations with every orifice, including pores, of a certain woman. The woman, of course, must survive this, as it is tradition to give a congratulating participation medal to her.

Have you seen my girl, I'm her Gumphumper.
