TMI 

An acronym used as a “time out” or “let’s change the subject” protest on Instant Messenger. Stands for TOO MUCH INFORMATION, indicating that the speaker feels personally violated by his chat buddy’s latest message, probably because it contains details that are either too personal (i.e.: sexual, medically-private, describing one’s deeply-rooted fantasy, etc.) or are of the type that would likely turn one’s stomach, being revolting, gory, or otherwise overly graphic.

Online guy #1: I felt sick yesterday after a “hot’n’heavy” session with my plump new co-worker, so I had to have my stomach pumped, and the contents examined. There were some residues of lipstick, but at least there were no weevils.
Online guy #2: Uhhhhggggghhh… TMI, dude…
