I've got one. Inconsiderate slow cyclist filters to front and jumps the light intersection after intersection requiring other cyclists to repeatedly overtake.

I was riding home from work today (in the bike lane) and stopped at a light. As the light turns green and I'm just getting going a cyclist overtakes me to go through the light. Fair enough, because she never had to stop for the light, but I was already thinking "Oh great, you're going to make me have to pass you in a few seconds...". Of course I couldn't be sure the girl who passed me was going to be slower, but judging by her dutch style cruiser bike with the saddle way too low for full leg extension I was 99% sure. And, I was right. There was no traffic behind us and I easily passed her until a minute later I stopped at another light. Several seconds later the girl I passed pulls up behind me, and then filters in front of me into the pedestrian walkway. As soon as the light for the through traffic is yellow, she's gone. This time I'm thinking "freakin hell, now I have to pass you again!". She seems completely oblivious. This time there are cars behind us, and we've caught up to a third even slower cyclist. I shoulder check and see a car approaching. The girl in front of me then pulls out to pass the slower cyclist, with not as much as a glance. As she realizes that she's about to be sideswiped by a car (its too late for the car to stop) she squeezes the cyclist she's overtaking into the curb nearly taking both of them down. What a dolt. After that gem, I had a good mind to have a chat with her at the next light about the etiquette and safety of filtering, overtaking and shoulder checking but I held my tongue. After the car passed I overtook both cyclists in front of me only for the girl to catch me again at the next light. The girl again tried to jump in front of me. I really wanted to tell her to wait her goddamned turn, but figured it probably wouldn't be a productive conversation for either of us. Instead, I also jumped the light so as not to let her get ahead of me (I don't like doing it, but didn't have a much better option). I made the subsequent light, while she didn't, and so was finally rid of her for good. So, blond ponytail girl on the Dutchi bike with with designer shades and filp flops: If you're reading this please please please don't force other cyclists to repeatedly overtake. And if you like jumping lights, please don't force other cyclists to also participate in this illegal behavior in order to stay in front of you. Damn Freakin' Straight.
