A boy, usually between the ages of 16-25 who will manipulate and lead you on with the intention of fucking you. After he has fucked you, he will either abruptly stop talking to you or slowly cut contact. Fuckbois come in all shapes and sizes. Always ask for nudes. Usually wants to "watch Netflix and chill ;)".
"Rob hooked up with three different girls this weekend, but he said I was the only one for him. He's such a fuckboi."

Get the Fuckboimug. 
Fuckboy behaviors involve using deception for sexual gain and ego, followed by disregard for the other person.
They claim/imply that they are interested in More Than just sex .
However, after the sex is completed, No or low-effort interactions are shown.
Primary Motivation: primarily(solely) interested in sex and personal gratification, and nothing more.
Deceptive Strategy: Create false expectations in the other person by Saying and/or implying they want more than physical intimacy, specifically to achieve the goal of having sex
True Intentions: Have sex with the other person, and then disengage relationally.
Post-Sex Behavior: Once the goal of sex is completed, behaviors shift and contradict previously stated claims.
Relational disengagement includes contact that shows reduced interest, emotional withdrawal, ghosting etc. It can happen even before parting ways.
Cause: may result from insecurity, attachment avoidance, emotional immaturity, asymmetrical personal gratification, narcissistic traits etc
