Pulling a Starkweather
The act of setting up Claymores up around a house and baiting in the enemy team to get cheap kills on Call of Duty 4. Most noobs, lazy kids, or just plain losers use this idea to get easy kills and/or challenges.
I went near the Broken Helicopter on 'Crash' and some fag started 'Pulling a Starkweather' and ruined my chances of completing my challenge.
