After a member of the team has made a speech, all players normally shout "Grish Uder" or "Grish Úder" or any number of other variations of the spelling.
After this, the players on that team buy Para m249 or other heavy duty gun, and go on a minigun rush.
The term was coined by a Counter-Strike pro player by the name of Anti, who's team won the 2006 Russian CS:S Tournement after playing a game where is team was 4 down.
