A man who believes his penis is God's gift to the world, but he does not know how to use it properly. A man who does not know how to please women sexually.
This term originated in 2018 when a group of women were describing very disappointing sexual encounters with men.
Monica: "I heard you got lucky with Trevor last night!"
Kate: "... we had sex..."
Sara: "Why the longface? I heard he was well endowed!"
Kate: "ya... but he's a total Dick Jesus"
Monica: "eew! Dick Jesus men are the WORST!"
Sara: "I don't care how beautiful his penis is, if he's a Dick Jesus, I'm not gonna waste my time."
An exclamation or interjection of anguish, usually that which is caused by another person's idiocy. Mainly used on its own, not as part of another sentence.
