Strecthgasm is a combination of two words. Strect and Orgasm.
Stretchgasm is the feeling you get if you wake up in the moring and you stretch. You feel go and your muscles get relaxed. It feels like an orgasm but more on the backside.
Stretching for staying in one spot for a long time.
Person: Damn what a stretchgasm!
The feeling of relief
after a long, full-body stretch.
I just had a HUGE stretchgasm.
This is when you stretch so good your entire body begins to shakes and you feel like a new and happier person.
"Hey, why are you so happy?"
"OMG I just had a stretchgasm man, such a natural high!"
