What does lkr mean in text messaging?
LKR is not a known texting acronym, but you are likely referring to "IKR", which stands for "I know, right?" This is a common text messaging response indicating strong agreement with a statement another has made.
This shorthand became mainstream with the 2004 movie "Mean Girls" starring Lindsay Lohan and has been popular in texts, chats and message boards ever since.
Mean Girls debuted on April 30, 2004, when Lohan (born Lindsay Dee Lohan on July 2, 1986 in New York City) was only 17 years old.
