An overly macho/aggressive/impatient golfer who compulsively feels the need to "swing low" and therefore not only really clobber the ball, but also to totally annihilate the tee that it's resting on, not to mention gouge out about three inches of grassy topsoil along with it.
The new golf course in town has an additional rule to reduce their turf-restoration budget --- not only do they have the standard "profanity and aggressive behavior prohibited" notice, but they also strictly forbid teetotalers... if you wanna play here, you gotta behave yourself.
A teetotaler is someone who doesn't drink alcohol, be it for religious, moral reasons, or just personal preference, such as not liking the taste.
I am a teetotaler because I am very prone to developingbad habits, and am worried that if I did drink it would become another addiction/bad habit. Therefore, I will not use alcohol under any circumstances.
