50 yard cockblock

the act of cockblocking someone from a distance, this could be because you dont want one person to get with another or simply to ruin a party.
It is usually achieved by doing something outrageous or dangerous so you attract everyones attention in a certain area, such as running around naked at a social event.
It is also used by guys to stop their buddy's beer goggles as usually after such an event the effects of alcohol wear off slightly and judgement improves.
