Swedish word for a young girl or boy who is stucked up and stupid. The Fjortistjejerna (fjortisgirls) often wear stringtrousers and tight jeans. They like to put their breasts in your face and giggle very loud. The fjortisboys think they are cool and might be mistaken for bögar (swedish word for queers) The fjortisarna are between 13 and 15 years old. They are often seen driving their mopeds, or måpar, or drinkin alot of sprit (lickor)that they can´t handle.
