The Sun claims to have read the screenplay for the E4 comedy's first cinema outing, which will see the hapless foursome head to Malia for a lads holiday.
The publication reveals that at least three of the main characters will land romantic interests, as Jay (James Buckley) pulls what he dubs "a fat pig from outer space", Simon (Joe Thomas) charms a female confidante during his ongoing quest to seduce Carly (Emily Head) and Neil (Blake Harrison) "bends one in" an older dinner lady.
The programme's protagonist Will (Simon Bird), however, is believed to spend the entirety of the trip sporting a phallic-shaped sunburn.
Other cringe-worthy highlights revealed by the paper include the gang's attempts at "suicide shots", an ill-informed island tattoo and a near-drowning during a boat trip.
The Inbetweeners movie is expected to be released on August 19.
