anti woofer tweeter

An electronics project consisting of an oscillator and a high RMS wattage tweeter. When run it generates an high-powered ultrasonic sound that annoys dogs and causes them to stop barking (woofing).

My neighbor's dog was keeping me awake at night so I fired up my anti woofer tweeter so I could sleep.

Anti-contender 

(1) An individual, object or situation that is either involuntarily or voluntarily not part of a tournament. This could be due to an injury; not meeting the standards and requirements of the tournament; or, in the case of an individual, he/she is actively able to decide to remain out of the tornament. Generally, objects and situations do not have the conscious choice of being an anti-contender, however, an individual has the liberty to choose whether or not they wish to be a participant.

(2) an individual who enjoys playing board games, strategy games and sport related games but does not participate or wish to be involved in playing games with people's lives, including their own. Generally a very straightforward person who can not watch another's life being played with and doesn't appreciate their own being made a toy.

(1) i. The javelin snapped just 5 minutes prior to the tournament and was immediately called out as an anti-contender for the entire comp.
ii. Tiger Woods fell ill days before the PGA tour and thought he'd best sit out as an anti-contender for the rest of the tournament.

(2) i. Peta loves playing basketball for the school team and bingo during her spare time but she does not play dangerous games with peoples lives. She enjoys board games but doesn't believe in gaming with life.
Example:
p1: "Peta, you can dunk a ball well but you're an anti-contender..."
Peta: "Yeah... that's just the way i am. To me, we don't make a game out of life, we make a gift out of it."
p1: "Fair enough."

Anti-Tebow 

The lack of having self-confidence. Not believing in yourself or your team. Being a detriment to a situation, instead of the solution. Being a Hater. A modern day Antichrist.

The kicker missed the extra point. He was the Anti-Tebow. That guy was so negative, put me in a bad mood he was the anti-Tebow.
