Periscope

When the tip of a recently erect penis peeks over the waistband of underwear, shorts or swim trunks.

I was at the beach and saw Jeanie and got a boner that turned into a periscope. Luckily, no one saw.

Periscope

When the end of an exceptionally long turd sticks straight up out of the water.

Similar to a "breach" (where the turd will arch up out of the water) but fully vertical.

Both of which, really really stink.

Dude, I just totally dropped a periscope in there.

Cock Periscope

When you stick your penis out of the sunroof of a moving car.

Sometimes when I get bored my friends and I drive around and cock periscope everyone.

periscope

signing on AIM, checking if your stalking target(s) is there, and signing off if she's not, giving the appearance of a periscope breaking the surface and submerging again

It's damn creepy how Ben periscopes for Martina every night after their breakup.
