naked sit-up
When a guy tries to suck his own cock while doing a sit-up and ends up looking like a confused chicken on a treadmill.
My cousin tried the naked sit-up and fell off the bed. Now he sleeps on the floor.
At the gym, I saw a guy doing the naked sit-up and he looked like he was trying to escape a vacuum.
My brother says he does the naked sit-up every morning and it’s his version of meditation.
