My usual 4 some consists of myself, my roommate, and two friends. My two friends are better than myself, they usually shoot mid to high 80's and tend to follow the rules of golf pretty well, and so do I. Now my roommate, he cheats his ass off.
Me and my roommate go out one early morning. I card a 112 (around what I usually score). He claims to card a 104 (his normal is about 130).
So I'm like WTF, I was ahead of him on most shots, and I constantly had to wait on him skulling and chunking all over the course. There's no way he scored a 104.
Of course he brags to my two other friends about how he beat me and scored a 104, claiming his irons were straight as an arrow, and his 4 iron is his go to club which he can his consistently. Mind you, when all of us practice at the range, this guy slices an 8 iron. He has a terrible swing. Very handsy, no leg action, all shoulders and arms. He refuses to get lessons because once in a while he'll hit a decent shot and claim he can hit it all day.
Naturally, none of us believe him. the next time we all went out, one of my friends kept his score. A magnificent 142. Every time after that, he hasn't scored below a 127, but still brags about almost breaking 100.
For months this went on, we noticed him shaving strokes, improving lies, taking 5 foot puts, not counting putts, etc. It actually became an annoyance that he cheated. If I did the things he did, I'd be shooting low 80's and my friends would be on the PGA tour!
At this point, I'd rather play by myself than have the chance to play with him. I just hate how he would cheat, then brag about his scores.
