Suicide
From YoYo Wiki
The suicide is a trick invented by Steve Brown based on the diabolo trick of the same name. In it, you release the trapeze loop and catch it again on your finger.
Throw a breakaway and proceed to land into a Trapeze. Once you get in the Trapeze, swing your non-throwhand hand under your throwhand and flick your finger upwards slightly as you release the loop. Once you release the loop, the loop should continue to travel in a counter-clockwise circular motion just in front of your throwhand. When the loop gets near it's original Trapeze position, insert your finger through the loop and "catch" the suicide.
