Travis Barker: Dammit, Feeling This Finger Grind Off SUCKS!!!

Travis Barker is a badass with sick drumming skills cause not even a blood-spraying finger can hold the man down.

The Blink-182 drummer lost a chunk of his finger after going all hardcore at a gig in Ohio. After the show, Travis posted a pic of the horrifying injury. Check out the pic ... but you've been warned.

The band's playing a bunch of shows until the tour ends Oct. 7 and we're told he's rockin' on -- with or without his finger.

Someone get the man a first aid kit.
