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. )
Sally had a cold and felt like shit, so instead of getting too wild and crazy with Tod, she just coughed in her hand and gave him an Ian Phlegming.
A good measure of nasal phlegm, hoiked up and spat on a ceiling. The desired effect is to have a thick, glutenous ball of spit slowly hanging into an icicle type installation, the better right above teachers desk. Joy occurs when the phlegmsicle starts its journey and becomes ever more elongated, until the tipping point is reached and the phlegm disconnects with the ceiling and becomes an earthbound projectile of slimy green snot.

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.
