A code word meaning smoking weed. Scuba divers dive down deep beneath the surface of soberness into the depths of the ocean to explore the coral reefer.

Spending an excessive amount of time in the bathroom/loo/privy, especially when others need to use it. Scuba Diving can interfere with other peoples' busy schedules, as there is much time wasted. Whilst sometimes a person may spend a long time on the toilet due to legitimate natural reasons, roughly 80-90% of Scuba Diving is caused by reading newspapers, making phone calls, or playing around with electronics devices. Scuba Diving can be done by both men and women, but under different circumstances: for instance, women naturally spend absurd amounts of time in the bathroom usually messing around in the mirror as is, whilst men can spend about 30 minutes on the can playing Angry Birds or something.

The term comes from the idea that the reason why the person is in the bathroom so long is because they're literally swimming around in the toilet water rather than doing their intended business.
Ted: For Christ's sake, man, Billy's been in there for like 45 minutes! I have to take a piss really bad!
George: I know, me too -- what the hell is he doing, Scuba Diving in there!?

Roger: Damn it, I got to shit really bad, but there's only one available stall in our building's men's room, and some damn old guy's been in there for ages with his newspaper. God damn it, I hate Scuba Diving!

Jason: Dude, we've been waiting for a fucking long time to go and pick up our pizza. What the hell were you doing in there, Scuba Diving?

Similar to a "snorkel" in which a tall man (a spaniard, for example) leads a much shorter man (e.g. a slavik dwarf) into the sea. When the water becomes too deep for the dwarf to breathe without swimming, the taller man forces the dwarf's head under water and shoves his cock in the dwarf's mouth, mimicking a snorkel. However, scuba diving requires an even taller man (a Pollock, for example) and a much shorter man (a Japanese man), and the two explore the deep crevasses of the ocean floor.

Especially effective if the Japanese man is only half Asian, as he will be less vindictive in the case of resurfacing.

Mom knocked on the door while I was in the middle of scuba diving and I took another womp before getting out of bed.
