A cross between an accident and a suicide; when you don't know which one played the part in a death. Referred to in John Green's novel: Looking for Alaska.
"We'd never know if her death was an accident or a suicide, a suident."
A strider is someone who uses their strong burst speeds ("striding" or "hitting the stride") to achieve very low sprint times when compared to their versus skill.
Striders may also be known to restart a lot when sprinting, due to their desire to make every run perfect.
I am a strider, so I am not very good at versus matches
"Pfft Opal, you stride and get 80APM"
