Periscope 

When an individual discreetly checks out someone they deem desirable or attractive.
Emphasis is placed on viewing the individual without being caught. Similar to how a submarine would use its periscope to view a target without being discovered.
Those versed in periscoping are exceptional at situational awareness. They are able to enter a room and quickly identify the most attractive individuals without being caught.
Direct staring is considered a novice technique. Advanced periscopers will utilize mirrors/reflective surfaces to view their targets.

Did you just periscope that girl man?

periscope fart 

When you press your butt against a hard, flat-surfaced chair and fart, but there is no place for the gas to escape except up the crack of your ass. and out at the top.

Dude, I laid the biggest periscope fart in detention. I press my butt cheeks against the hard chair and farted and the gas came bubbling up the crack of my ass and peeked out at the top!

periscope depth 

When a fresh a deuce is so large that it breaches the surface of the toilet bowl water, exposing the tip to air.

The toilet bowl is designed to use water to contain the terrifying smell of fecal matter. Naturally, when a load is large enough to reach periscope depth it stinks up the bathroom something terrible, requiring a courtesy flush.

"Whoa dude, did you just dump all of Bombay in this bowl? My fuckin nose is going to fall off"
"Sorry after all that built up sushi that dump reached periscope depth"

periscope depth 

When your penis persistently peeks through your underwear fly, regardless of how many times he is readjusted, thus increasing the risk of tip zipper rash.

Hold on a second I need to adjust my drawers. My junk keeps playing a shadowy game of penile Groundhogs Day, you know,... I've been cruising at periscope depth all day...
