Has your friend said something funny to you via Facebook chat messenger? If so besides sending the obligatory ‘LOL’, ‘LMAO’, or others why not send them this Purple Alien Laughing Facebook Emoticon. Sending this emoticon to your friends will make them feel that whatever they said was genuinely funny, and make them feel all warm and fuzzy inside. Besides it is always better to send a nice emoticon than just sending back just a quick line of text.
