An inbetweener, as implied by the name is a male neither a boy nor a man,it is that perfect inbetween stage where looks are still pumping strong but nothing is yet wrinkled.
Also this stage allows for the awesomeness of a younger male with the maturity of a man.
An inbetweener is not fickle and wants to have fun.

Girls love the inbetweeners because they are the perfect combination.

He is the perfect inbetweener for me says sally to joy

Inbetweener 

A hermaphrodite.

Nobody could tell that Jordan was an inbetweener, despite the fact that she had a luxurious happy trail on her six pack, and that she's had pubes since she was in Kindergarten.

Inbetwiener 

When your sexual organ is in between a vagina and a wiener.

"Oh man, his penis is so small it could be a clit, he's an Inbetwiener! Hey man, some chicks dig that."

"Look at that giant swollen clit! That Inbetwiener is just aching to get pounded!"

"Nah man, Tranny isn't politically correct! Call her a Inbetwiener!"

Inbetweener 

A person who isn't super popular or with the "in crowd". But not a bottom scrubber with the losers at the bottom of the social pyramid

Mike, Dave, Liam, and Barry are not cool enough to be with the cool kids but not a bottom scrubber like the geeky anime/emo/gamer lot. They are the inbetweener people.
