Goo blobs that lurk in the back of your throat waiting to make you sound like a wounded bird when you try to talk. They can sneak up on you without warning.
I was giving a speach to the entire class when I got a bad attack of Phlegmingos.
When a girl hocks up a loogie and uses the mucus as lubricant to give a dude a hand job. Named this way in honor of the British writer who created James Bond, Ian Fleming. ( No other relation to the sexual act other than his last name sounds like phlegm. )

A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
