look up anything, like your first name:
1. Acronym Chat (AC)
The use of acronyms in everyday conversation. Taken from the instant messaging chat speak way of communicating.
Teacher: "I'd like you to do your presentation first please"
Student: "N.T.Y."

This student is saying "No Thank You" using Acronym Chat (AC)

However 'lol' is usually said "lllolll" rather than L.O.L so would not classify as an AC.
