But this demands deciphering.
"high clip just puts a bullet in the sniper and shotgun worthless"
I really feel what he is trying to say is that the adjective "high"; metaphorically speaking, is superior, near God-like. Clip of course is the noun, perhaps his IGN. "High Clip" is of course, a very able marksman whom never misses. 'just puts a bullet in the sniper" speaks for itself. And finally "shotgun worthless", certainly against a skilled opponent such as High Clip, shotgun is utterly worthless.
