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.

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.

Days that arent good and arent bad, but you still need something.

A day where you are missing something or someone.

A dance, featured in the British comedy film The Inbetweeners Movie always to the tune of We speak no Americano by Yolanda Be Cool. The dance is ironic as all the moves are quite awkward and very simple, like a piss-take macarena. Sadly though, the dance is an inside joke with the majority of the uk, who have seen the movie, and as the film has not been released overseas, anyone from outside the UK will have no idea of the dance's funny origin, and just think they are being strange. If they had heard of the dance, or seen it before, the chances are that they have seen the British boyband One Direction perform it and incorrectly assume that they made it up, with humiliating consequences for any Brit abroad.
"...So I was at this club, not doing much, when suddenly 'we speak no americano' comes on, and simultaneously, everyone in the club starts doing the Inbetweeners Dance in sync! WIN!"

adj. metonym. A day spent evading from one's otherwise usual responsibilities (work, school, babysitting etc) with one or more other people, in the pursuit of a more fun activity - typically drinking, vandalism of driveways and other such anti-social behaviour.

Inspired and popularised by Episode 2 Series 1 of the Channel 4 (UK) television show The Inbetweeners.
Me and the boys had an inbetweeners day last Thursday - it was great, we beat all the queues at Thorpe Park.

Sensible Steve: Aight, safe.

Greg did not approve with the group's decision to have an inbetweener day on Thursday. What a bumder.

To be in-between ugly and cute means that you aren't ugly, but you aren't cute either. You have both attractive and unattractive qualities. You are of neutral appeal.
Zachary is inbetween ugly and cute, I would date him.
