John: I think that Alice and Mary are going through suicycle.
Peter: What's suicycle?
John: Oh, it's the cycle in which you go through when you feel like you want to commit suicide.
One who, while dressed in brightly coloured silly clothes and an inadequate helmet, rides a (racing) bicycle (often in heavy urban or rush-hour traffic) at high speed and without signls, as if they have no interest in their own safety or that of others, and genuinely wish to die as soon as possible in a multi-vehicle collision of their own making. They invariably look offended if forced to give way to cars, whatever the circumstances. See also kamikaze.
To ride your bicycle in a very dangerous way, direction or area of town without brakes.
esp. without helmet, the wrong way down a one way street, on the freeway, or in Houston, TX.
