What's worse than a sore Loser?
Damn near nothing.
The coach took his ball and went home. That's just sad right there. I remember playin' baseball early in life, I had a great game and my team just sucked like vaccuum cleaners. I remember watching how much of a prick the opposing coach was acting like when they won, very demonstrative and loud and whatever so when we all lined up, I didn't shake his hand. I guess I shouldn't have been surprised, he made a big deal out of that too and I was forced to do so later.
Point being, he was a douche regardless of what I did. So I may as well shake his hand and not stoop to that level.
This coach, or...GUY because I doubt he coaches much longer, just pulled a no hand shake x a couple million. Watch the video, they walk off the field while people laugh and boo.
