Has anyone ever tried this? The term comes from the Latin: inter for "between" and crura for "legs". Oh, the joys of a classical education.
Anyway, it does what it says on the tin. The "active" partner inserts his penis between the thighs of the passive partner and thrusts back and forth until climax is achieved. It's non-penetrative and completely save from an STD point of view. It was huge between guys in Ancient Greece it seems. It's also quite common in some parts of modern-day India apparently.
