an inside joke in the U.S. military played on 'Boots' (newly arrived from boot camp).

squelch is a term used to fine-tune radios. it is a knob or button that controls whether or not background noise is heard on an open channel. it is used when communication is poor or lost and you are scanning your frequency/channel for any recognizable sounds.

telling someone to get a 'can' of squelch sends them to go ask someone, causing everyone who knows the joke to laugh. this is not always wise to send a boot to a Senior NCO for.
0311: hey Boot!

Boot: "Corporal?"

0311: "go down to supply and get a can of squelch. this radio's been acting up all morning and i can't get comm."

Boot goes to supply, waits in line, and then gets yelled at for wasting supply's time and their own. Usually ends with the Boot cleaning something unimaginable or guarding something insignificant for long, long, periods of time.

The noise made when you are in the bath and you "take care of yourself" above the water, but some water has got into your foreskin so it squelches, this is usually done instead of below water as the splashing noise usually gives it away, however dick squelches are even more obvious then below water "dick splashes".
"Alex, whats that noise? are you dick squelching" "no mum!"

The Squelch-Meter is the only accurate way to measure a woman's pussy squelch. The meter goes from 1-10. Pussies with a squelch of 1 have dry ass, Sahara desert pussies. Pussies with a squelch of 10 have wet, drippy, Niagara Falls pussies. A 10 is the best score, but pussies with a squelch of 6 and up are acceptable. The squelch is more important than any other rating a woman can receive.
"Damn bro, Sydney's pussy was a fuckin' 4 on the Squelch-Meter. I'm never hooking up with that bitch again."
