cockblockery

The art and practice of cockblocking, generally in reference to intentional, rather than inadvertent, acts of cockblocking. However, this term can also be used to describe the tendencies of a person who possesses a certain oblivious demeanor that lends well to unintentional, albeit frequent, cockblocking activity.

A male who unwittingly(out of ignorance) or purposefully(out of jealousy) prevents another male from engaging in debauchery with members of the female sex.
