As you all might be able to tell, this taunt is quite similair to the rancho relaxo.
In fact, i think its a little bit too similair. Maybe add some characteristics of sniper into it and as someone else suggested, make it coffee not beer. This would already seperates the two slightly.
Maybe add something so he could shoot from his chair (in theory, not as an actual attack. Just like there are houses for npcs who never move from their spot in a RPG game. )
