Muff-Diving

Searching for a fat girl's vagina to initiate intercouse while layers and layers of blubbery lard get in your way. Thus making a diving maneuver completely necessary.

Guy 1: "Yeah, dude, I totally fucked ____ last night."
Guy 2: "Isn't she like 200 pounds though?"
Guy 1: "Yeah. I was totally muff-diving but it was worth it."

Double dicking

When a man inserts his erection into his female partners vagina and at the same time uses an equal size dildonic device in her asshole.

Last night I tried "double dicking" my woman, stuck my dick in her pussy but her John Holmes replica dildo for her ass ruined it for me!!!

Pre-Emptive Deep-Sea Diving

Pre-Emptive Deep-Sea Diving is when, after taking an enormous shit, you pre-emptively stick your hand down in the toilet water and break up the gigantic turd BEFORE you flush, therefore avoiding an embarrasing overflow situation. Suffice to say, some prepartion is necessary. (If the situation around Uranus requires you to wipe immediately, just "stage" the used toilet paper (TP) on the edge of the bowl and flush them AFTER the crisis has resolved itself. Otherwise, wipe later. 1) Wad up a bunch of TP ahead of time, to be used to clean off your shit-stained finger tips after you've done the deed. 2) Pull your pants half-way up, just in case there is a flood. 3) DIVE!, DIVE!, DIVE! Stick that hand right down in there and start breaking that turd up. Don't be afraid to overdo it. 4) DON'T WIPE YOUR FINGERS OFF YET! Use your clean hand to flush, then quickly cross your fingers for good luck. 5) If all goes well, you've successfully dropped the Cosby Kids off at the pool. Congratulations! If it didn't work, skip Step 6 and proceed immediately to Step 7. 6) Use your pre-saved wad of TP to clean your fingers off, then drop the used TP in the bowl. Proceed to wipe your butt (or if you've pre-wiped, tap in the used TP) and drop the TP in the (now) nearly empty bowl. Whew! 7) If the poop break up did not work (or you were too pussy to do it!), quickly hobble out of the stall to the next stall and finish your paperwork there. Act innocent.

Ollie: Well, Stan, that was a delightful and quite filling meal. Now, if you'll just excuse me for a moment.

Stan: Don't forget about Pre-Emptive Deep-Sea Diving! (smiles sheepishly and scratches top of head).

Ollie: Indeed.

Dining at the Y

A euphemism for performing oral sex, usually cunnilingus, as others have mentioned. "The Y" is also a nickname for the YMCA, once a famed hangout for trolling gay men. Also, only men have a Y chromosome, so dining at the Y could also mean fallatio, or perhaps analingus as well.

What are you guys eating tonight? - Oh, we'll be dining at the Y.

Cliff Diving

Doing a dance resembling the Harlem Shake while hiking. A term invented by the hiking community that got bored and decided to dance while they hike. The term is used to scare people and cause people to infer that people are jumping off of rocks into pools of water.

"We totally were cliff diving, and my dance moves are legendary!"
