Verb- to completely destroy something, especially in a warehouse setting.

Man, you really jeff'd that pallet! Now we can't even use it!

That act of destroying something for logistical purposes because you have no damn clue what you’re doing. This is most predominately displayed at Apple by COO Jeff Williams and VP Evans Hankey.

The act of not getting rid of the iMac chin is a Jeffic decision.

When you get a meaningful tattoo and the tattoo artist free hands the Calligraphy and just ruins it completely.

When you see your tattoo for the first time and it says jeffica not jessica and every laughs at you and life falls apart!

When a male pops a female right in the kisser -with closed fist- after she has given him a remark that he doesn't agree with.

Comes from an old Chiro member (Jeff) that was the first to practice this form of art.

Seune got a vicious comment from that girl. It wouldn't surprise me if he gives here a good ol' Jeffer... That'll shut her up right quick!
