Hobo Rat Knob
If two hobo's want to have sex but do not have enough money for condoms or to support a baby, the male hobo grabs a rat and impales it through the rat's anus , onto the mans dick, and then the couple have sex.
Oh man, Coby spent all his money on cigarettes so he has to use a Hobo Rat Knob!
