Pinging a list of others to come join in a beat-down on someone you should face mano y mano, is pretty disgusting behavior, in my opinion.
I grew up in a hard place where street thugs did that on a regular basis. The cowards would never go toe to toe with anyone they tangled with. I used to beat suckers like that to the pavement in my youth, and had to confront their 'posses' on more than one occasion.
I see the same thing happening here sometimes, and the dynamics are exactly the same as those street gangs I once fought with.
It's plain cowardly, and I won't do it. If I've got a beef with someone, I take it up with them one on one.
He always takes the coward route after getting whupped on and pings his posse like a whiny baby cause he can't handle it alone.
It's a pretty despicable trait.
Treachery and cowardice, much like Rabadash the Ridiculous.
