in saiki pissy boo world server, an admin called talia went afk for like a whole ass 3 months with "breakfast lololol" as the message. it is an expression used to highlight being gone for a long time.
Are you a chatter? Don't like using the expression "lol" because it makes you look like a 13 year old, insecure girl, but you still wanna express to your significant-interwebz sweetheart that you're laughing out loud? Then lollak is just for you! It express the act of laughter, but still in a cool/hip/original/urban way! Only use lollak when you really wanna express laughter! To the extreme! Lollak!
