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.
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.
When an allen wrench is inserted into an orifice (anus or vagina) and gingerly twisted around, by which the insert-ee can feel sensations that they normally don't feel with an ordinary probe.
My dildo feels great, but that periscope touched me in ways that I've never felt before.
A bit of stem that is poking through a rolled blunt.
That blunt had a huge periscope out the side, but it still smoked just fine.
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.
When you get a boner in the bathtub, and it looks like the periscope of a submarine
I walked in the bathroom and he totally had a periscope!
The act of agressively fisting a female (or a male) into the vagina or anus hole, then rotating your arm inside the victim left and right, like a periscope, then yanking your arm out.
