Play Music on your mic, because people love this.
When the music stops.
Reclaim a structure, pick an important one, and put it up somewhere else in your base.
Play music again.
I like to harrass my own team when I can not switch to help out with a BR.
Take some fruit with you: This involved throwing a prox mine on a freshly spawned Razorback which the knuckleheads intend to take to the other base and run over noobs until they get blown up
It wont start: Repeatedly getting on an off of sidewinder (or sitting there continuesly switching weapons) in the corral and watch the line form behind me. Should they spawn a new coral then they take some fruit with them
I was in a room last week called "Wall builders of Retardia" It consisted of a few level 50+ guys trying to train noobs. I was on my buddies PS3 using his alt (a level one). The fellow hosting the room was lecturing on the evils of wall building. Meanwhile his stacked team was repeatedly taking our flag. At five captures the thefts stopped and the lectures started back up. I in the mean time had built a sauvastika (look it up) just outside the base knowing the next time they flew over to CB us they would see it. The reaction was priceless.
In the next game I ended up on the same team as the host and lecturer. He spawned a Grizzly and everytime he got out of it an errant rocket or grenade would set it on fire. He eventully kicked me when it became clear to the other 50+s on the team this kind of thing was happening to all of them.
