Sclenching 

The act of holding in a fart you’re about to expel, in order to avoid obvious and general embarrassment. Usually they still squeeze out but with no sound and not as deadly.

Guy1: “omg last night with my gf I was holding in the biggest bomb when we were making out.”
Guy2: “you should have dropped that shit Hiroshima style.”
Guy1: “dude I like this girl, trust me I was sclenching mad… as soon as she left though my room smelt like Indian food cooking over burning hair with some garbage on top.”

Clenching Chowder 

What happens after having unprotected anal intercourse with a man with a tiny penis. The ejaculate doesn't get past the Anus Hotel lobby (so to speak) and coagulates very close to the one and only exit; occasionally causing a bloated feeling or general lower GI discomfort.

After they found him half naked with his scout master in the closet, he ran to that restroom so fast you just knew he was clenching chowder.

Neurotypical screeching 

Non-autistic people getting worked up over something unimportant.

I see a celebrity who always says stupid things has said something stupid again and the neurotypicals are treating it like it's a big deal. What a load of neurotypical screeching.

Screeching Locust Blow 

This is done when one places a Chinese whistle in their ass hole. The whistle holder is then assisted by their partner, who breathes heavily into the securely mounted whistle until maximum pressure is achieved. Then the assistant removes mouth from whistle and immediately punches the whistle holder in the belly. The force from the blow will create the sound of a screeching locust. This works even better when the whistle holder is wearing some fluffy angel wings and green goggles.

I was worried last night that I would wake the kids when I gave my wife/husband a screeching locust blow, but they managed to sleep right through it. It's a good thing, because that would be a tough one to explain.

Clenching 

When a woman's uterus and vagina contract causing unbelievable pleasure course through her body.

My lower belly clenched in anticipation of his cock. I could imagine it like it was happening. As my vagina was clenching, all over my body pleasure ran through my veins.
