A seatbelt strangle is when your seatbelt decides not to let you free, and every time you try and move so it loosens, it only gets tighter. Ususally this occurs when you try and loosen the seatbelt aaalll the way, to the point where it wont go any farther-the belt will slide back into place, and suddenly you find that you wont be able to lean forward. Because of this trapped feeling, you start to panic and hyperventilate and soon need the help of another to unbuckle you, and save you from the Seatbelt Strangle hold.

Afterward you are ususally exhilarated and happy that you defeated an inanimate object and escaped the clutches of teh Seatbelt Strangle.
