A word used to describe those who are extrememly bangin'. It cannot be used on those who are just hott. You have to be hott and THEN SOME. You have to be utterly orgasmic and make women croon whenever they see you to be dubbed as Hott Tree House Sex. It can also be combined with other phrases. Like Cliche Cherry Poppin' Prom Night Sex.
Monica: Constantine was looking mighty fine on American Idol today
Katie: I LOVE CONSTANTINE! HE IS CLICHE CHERRY POPPIN' HOTT SEX IN A TREE HOUSE!
