|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"
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.
