assthritis 

any aching feeling in your gluteal muscles. It can be caused by either overexertion or lack of activity. Some common causes of assthritis include office jobs, long trips by plane or car, and lower body exercises.

I got assthritis from that five hour flight.
The squats I've been doing have given me some major assthritis.
