Hammer

From Ultipedia

A type of throw employing the forehand grip, in which the disc is released upside down from above the head. It has a high, fast OI trajectory and is used to go over the crowd and drop to the receiver.

The IO analogue of a hammer is a thumber, but thumbers are seen much less frequently (even at elite skill levels).

[edit] Friends

It is worth noting that while you don't make friends with salad, you do win games with hammers.
