Big-dick

[Donald Trump]

To Big-Dick someone is to show them a lack of respect or ignore their presence. One might get Big-Dicked when attempting to high-five a peer or saying a casual whattup and receiving nothing but silent or getting no high-five response, even though the instigator is clearly holding up his or her hand in placement for the interaction. The phrase derives from the theory that male dominance lies in dick size, hence showing a lack of respect to those with a smaller dick. Instead to accusing the aggressor of challenging dick size, the term Big-Dicked was coined to indicate that the challenger thought they had a bigger dick.
One might address the challenger saying, Hey, are you Big-Dickin me? or they might speak about the challenger after the incident stating Wait a sec, did he just Big-Dick me?
