The type of guy a woman dates during her directionless phase and not caring whether or not he is a fully functioning adult with aspirations beyond being a basic fuckboy. More likely than not she is dating him till it gets boring and her ambitions will carry her elsewhere while he tries to recapture the glory of his adolescence but with no actual plan beyond where to "get lit." This is the guy that if a woman's period is late while dating him, she will legitimately panic because the thought of keeping him is absolutely opposite to the concept of a healthy relationship or for that matter a partnership in co-parenting.
