If I get really bored waiting for a PVP match to open up I'll go look for Klingon ships in sector space. When I approach in my assault cruisers I yell out something along the lines of "KLINNNNGOOOOOONSSSS SUUUUUUUUCCCCKKKKK!!!!"
I usually add in a spicy comment about how their cloaks will not spare them my verbal taunts. It's fun, you should try it.
"They broke seven of your transverse ribs and fractured your clavicle!"
"Ah, but I got off several cutting remarks which no doubt did serious damage to their egos."
