A server comes to check on your table, but stops because she sees all your heads bent over for grace… until she notices the glow from your mobile devices and realizes that your actually participating in SMP.

SMP 

A retarded TFC clan. They suck, but they think they are godly. They beat a couple of teams 9vs8 (other team having 8).

If SMP beats you, you either have 8 or less people, or your clan really sucks.
