Key binding:

To activate codes easier, bind them to keys. For 
example, type bind v "impulse 101" at the console 
window to bind the "$16,000" code to the "V" key.

Buy a flash bang. Find a corner wall. Walk or run
against it until you cant move any further (when 
you can't move from side to side or move forward).
Arm the flash bang grenade and aim at the center 
of the corner. Throw it. The Flash bang grenade 
would not bounce off instead it will be absorbed 
by the wall. It explodes around the wall (it
seems like it explodes everywhere!). All players 
within 20-30 meters radius will be blinded as if 
a flashbang exploded right in their face. A really
good strategy to piss off opponents as well as your
own team mates.
