Antiproton 

The antimatter equivalent of a proton. It has the same mass as a proton, but opposite charge (negative).

When a proton and antiproton orbit each other, they make protonium. When an antiproton and electron orbit a helium nucleus, they make antiprotonic helium.

Antipoon 

A term used to describe someone who is so bad looking or so awkward with women that they can't get any action. This should not be mistaken with someone who gets no action as these people will never get any action.
Can also be used to desribe someone who is well known to be a cock-blocker, who constantly ruins the chances of many people to get poon.
It is widely agreed that these people should be locked away or, better yet, put down.

Example 1:
Dude 1: Hey, you know that ginger dude at the party?
Dude 2: Yeah..
Dude 1: Well, he had this girl practically all over him last night and he still got nothing.
Dude 2: He's such an antipoon.

Example 2:
Dude 1: hey, you know that ginger dude at the party?
Dude 2: Yeah..
Dude 1: Well, i was getting with this smoking hot chick right, and he just comes barging in shouting "ohhh, you're getting it down there dude".
Dude 2: He did that to me once. What a fucking antipoon.
