Dogtrousers
Kilometre nibbler
Yes. And they are generally quite rude. And generally (but not exclusively) not aimed at other cyclists.Are there any types of cycling gestures used by cyclists where you live/ride/commute etc?
Less rude ones are the upraised palm after a close pass, that's the "Oh FFS!, there is no hope for you is there?". The forehead slap, meaning similar. There's also the feeble smile and nod saying "thanks for nothing" when a car coming down a steep narrow lane pulls over to let you up, so that you have to put a bit of extra effort in while the occupants of the car laugh and say "look at that old git struggling uphill, do you think he's about to die?".
For other cyclists there are the usual gravel and hole indications, typically only to other members of the same ride, and that wiggly double jointed behind your back pointing thing meaning "I'm about to pull out around a parked car, that I have noticed using my superior observation skills. I'm assuming that you will ride straight into it unless I do this wiggly pointing thing. You're welcome".
