What is Cock Shield?
1.
A guy friend that a girl will use to protect her from being hit on. It is preferable though not necessary for this guy to be gay. If a girl is not interested in a guy who approaches her she will suggest her cock shield friend is her boyfriend. If an interesting guy makes an advance on her she will assure him that the cock shield is merely a friend. An effective decoy tactic deployed by women in order to prevent the awkward advances of undesirable men.
"Dude what are you doing tonight? Wanna come chill with me?"
"Nah, sorry man I promised Kim I'd be her Cock Shield tonight"
