A sexual position where a female clings upside down to a male's front and sucks his genitalia (or a blowjob ) whilst he runs on the spot. If said female chokes or is sick, this is known as a Paula Radcliffe.
Cat: want to try some sick new sex moves tonight?
Matt: sure, like what?
Cat: the half marathon?
Matt: sounds like fun!
