When you look at a meme and feel either sad, hysterical, depressed, or laughing so hard that you are sent. There are a variety of emotions this is relevant to. You may catch your self swearing like a middle school drop out playing CS:GO, crying like a little bitch, saying "WHOOOOOO", or having a seizure.
a thing where you link through to something (youtube, a blog, and article etc..) and you see someone has recently left a message "xxxx...sent me here" or "im here because of...xxxx"
