A idiot who repeatedly sniffs knob, they also become addicted to the smell, a knob sniff is of the male sex.
The more extremists put the knob up their nose and sniffs till the cum fires up his nose.

Chris: no being a knob sniff doesnt mean you loose your virginity, you've had more pricks than a second hand dart board
