one who prevents one from engaging in pleasurable experiences with another person.
this scenario generally happens when the "cockblocker" is jealous because THEY aren't getting and if they can't have any then neither can you.

cockblockers come in many different forms. Such as the one upper, the show off, the moneybags, the never ending bullshitter and the man with the stuff.
