Frumpy-Load Kamikaze 

While paragliding and performing sexual acts, you release yourselves from the harness, timing your climax with the exact moment that you collide with the ground. As an extra bonus use the lady friend as a cushion. If you're lucky, you might bounce.

"Professor, what is the chance of getting pregnant while performing frumpy-load kamikaze-ing?"
"None."
"Werd."
