noise-to-signal ratio

The proportion of irrelevant, off-topic, inflammatory, nonsensical, spammy, screaming, content-free, trolling, or otherwise useless statements to actual useful, worthwhile communication.

From the informal sense of signal to noise ratio, but inverted to emphasize the "noise".
"That discussion board used to be a great place to talk about politics, but now the noise-to-signal ratio is through the roof!"

"Typically, a demagogue actually benefits from nonsensical, contradictory and inflammatory statements and agendas. Ironically, the higher the noise-to-signal ratio, the more effective they become since any useful information would actually rein them in."
(adapted from Raul and JonG)

signal suppository

n. A driver who accelerates when you signal to change into their lane, even though they have a lot of space to let you in. Very common in Los Angeles driving. Seeing your turn signal, they instinctually step on the gas, and get right up your a**, like a suppository.
I almost had a bad accident because I changed lanes and that signal suppository nearly rammed into me!

It's so hard to change lanes because of these signal suppositories!
