Dunce Cap

a small, cone-shaped turd, most commonly encountered stuck to the "head" of one's penis during withdrawal from an unclean anus.
"As I pulled my cock from her chocolate starfish in anticipation of shooting my load onto her bare butt-cheeks, I noticed a smelly DUNCE CAP adorning my head. Too late to stop, my load propelled the DUNCE CAP like a stinky poo rocket ship square into the back of her head, knocking her unconscious."

Caps Lock

Caps. Lock is a key on your keyboard located directly to the left of your 'A' key. As you know, capital letters are used for expressions that are meant to sound like they're angry or yelling, but, however..People abuse the use of the caps lock key and capitalize all of their letters to either sound excited or to be noticed. This is why a small organization has created a rule against caps lock being used for anything but the purpose for which it was created. This, is for three reasons.

1) It's incredibly obnoxious to read.
2) You just seem like you're angry all the time
3) There is no way for me to read that except for in a yelling voice.
PEOPLE WHO TYPE LIKE THIS ON EVERY SINGLE STATUS ARE INCREDIBLY ANNOYING AND NEED TO TAKE A TYPING CLASS IN WHICH THEY LEARN TO NOT ABUSE CAPS LOCK.
