A kind of fellow some ladies in search of an Alpha male may end up with.
The key distinction here is that instead of being the man's man they were looking for (charming, confident and entertaining), deep inside he's fundamentally still a kid whom:

1) is capable to ending up in trouble for doing shit as dumb as hell.

2) hangs out with equally maladjusted, immature friends.

3) may often show more interest in shit like Wrestlemania on TV, playing videogames and fidgeting idiotic apps than in an actual night out with his woman.

From the character of the old TV Series "The Little Rascals", a.k.a "Our Gang".
Woman1: "How's Sheena? I heard she got a new BF..."

Woman2: "Yeah, whom she tended to saturday night at the ER after he opened his forehead on a tree branch by riding stolen bicycles pissed drunk with his friends. Got picked up by the cops and they had to give him ten stitches".

Woman1: "Wow, I thought she needed her Alpha male..."

Woman2: "Yup she did, and she ended up with her Alfalfa male. He's 37, by the way".

Woman1: (eye-rolling)
