George is talking trash and then throws a beer at one of the 9 guys,
Are you talking about a bottle of beer, a full can, a near empty can, or just the contents of a cup?

If it was one of the first two, that is assault with a deadly weapon and George needed to get stomped in a boot party.

If it was one of the last two, that is being an arsehole and George deserved to be decked, but not stomped on the ground.
