LSD - A person who drops acid by licking a tab of window pane acid. Then this person gets weird and other people think it is okay to call this person a retard.
Guy One: Here dude lick this.
Guy Two: What is it?
Guy One: A lollipop.
Guy Two: It doesn't look like a lollipop.
Guy One: Well it will after you lick it.
Guy Two: (Guy Two licks the tab, and then questions Guy One.)
Guy Two: How do you figure that?
Guy One: The eyes are the windows to the soul, and you will see things differently after you lick it. Let me clue you in. That tab is window pane, but you don't have to take it if you don't want to.
Guy Two: What is window pane?
Guy One: Window pane acid.
Guy Two: wtf man this is LSD? I already licked it.
Guy One: I guess that makes you a Window Licker.
