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.
