Do you have Thai friends? I think if you have talked to them via emails, chatting programs or social networking websites, you might have seen “5555555” or “555555+” characters. These might bewilder you what they mean.
Thai Internet Slang
The number five is not any error or typo. It is only Thai Internet slang. Thai people pronounce the number five as “haa” so it sounds like “ha”. Therefore when Thai people would like to laugh while they are talking online, they will type “555” for “ha ha ha”. Many fives “55555555555” or many fives with plus sign(s) “55555555+(+)” can be used for LOL.
