hacker's ass - A burning pain in your ass from sitting too long like a damn

A burning pain in your ass from sitting too long like a damn genius. Hackers get this because they never move.

My ass is on fire from coding all night. Hacker's ass is real.

I sat through 12 hours of debugging. My ass is now a smoldering crater.

I tried to code while eating chips. Now my ass is like a war zone.
