Either that or he had ass removal surgery recently.
In the most non homo way possible I encourage you guys to do some squats or other glute exercises.
Your glutes are a vital muscle. They stabilize your pelvis and protect your lower back and work with your core. When your ass is gone your lower back and hamstrings overcompensate and stress your lower back leading to major problems.
May I suggest:
1) Daily chair squats and planks will help
2) Get your 8 hours of beauty sleep, make that 9 hours if you’re ugly
