He was hit with a blade from a ballistic knife from across the front lawn.

nipple knife

A nipple knife is when a females nipple gets really hard and could be used to cut open a potato or any other hard object a knife can handle.

Last night my girl friend had her nipple knife out cutting the potatoes and slinging them into the hot boiling water to turn them into mashed potatoes.

gents knife

An abbreviated version of gentleman's knife

A gents knife should be non threatening-looking, small and classy enough to not look out of place in an office and with formal attire.

A rule of thumb for blade length of a gents knife is less than three inches (as to not scare the sheeple)

Toaster Knifing

A sexual act where you carefully insert pop its fireworks into a condom you are wearing, so that when you stick you dick in, it causes them to all explode from the pressure against them. Much like the explosion created by jamming a knife into a toaster

Person: “Me and my girlfriend tried toaster knifing last night. It was painful but she says she wants to do it again”
