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.

when something makes you laugh so hard it “sent you”. Think of people in a group running away because something is so funny.

When something is so funny it basically sends you into orbit

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"

make someone laugh SUPER hard

Someone who sent you someplace with out for no reason makes you look stupid
