Let's see, lots of good material on this list, but a few more that are worth adding/propagating. Except for "brown ace," which is universal, most of these are terms just my friends and I use, but worth sharing because they always make me laugh.
"Brown ace" -- the term for when a hole has two or more permanent baskets on it and you ace the wrong basket (was playing with a friend who did this back in the spring). The idea here is that it was a totally fluke shot and you didn't hit anywhere near the hole where you were aiming.
"Teabag" - when you jump in a pond/stream to retrieve your disc and the water is waist high. As in "I had to teabag to get my disc back." "I could see my disc out in the water, but it wasn't worth teabaggin' to get it."
"Skirt" - used in a variety of ways to suggest someone wasn't forceful/powerful/confident enough in their shot. For instance, when someone's putt is short of the the basket, "Next time, take off your skirt and putt." Or for a short drive, "Looks like your skirt got in the way of your throw." Or in contrast, if someone has a risky shot and you want to advise them to play it safe, say, "Just put your skirt on and lay-up."
"Viagra" -- used when someone's shot is too low or plows into the ground, as in, "Nice shot, you just need to rub a little more viagra on it."
"Hey ___, it's you're birthday." -- said in a singsong voice, usually accompanied by an obnoxious dance, to try to distract the person throwing/putting. Not useful in tourney rounds, but great for casual rounds with friends when all distractions are fair game.
"Putting for the moon" -- related to the idea that all distractions are fair game, on more than one occasion on game-winning putts, a friend has stood behind the basket, dropped their pants and mooned the person who is about to putt.
"Carrollton Pimp Shot" -- this came about one day at Jimmy Porter disc golf course in Carrollton, TX -- we were playing and came up on old hole 17 and watched a big old guy rip a huge horking backhand hyzer out over the powerlines and down towards the basket. This was a pretty open hole with lots of good lines towards the basket. The guy's throw was such a gratuitous, unnecessary, memorable throw that it earned its own name. So huge, huge, huge full-power, super-high backhand hyzers that waste tons of energy (and can potentially dislocate joints) can earn this name.
"Futher-Mucker," "Son of a Drunken Monkey," "Flibbertigibbit," etc... these are great personal euphamisms for more vulgar terms. Usually, disc golf is happening in a public place, and we help the image of the sport if we are careful with what we say. Also, for what it's worth, I've never seen anyone enforce the rule, but you can get warned/stroked for vulgarity in PDGA tourney play. Find some good personal euphamisms for bad words... the best part is that you sound so silly that it's hard to stay mad. Usually makes me laugh and I forget my frustration.
I know there are lots of others, but those are top-of-mind this morning.
