Find the basketball hoop on the Detroit Streets zone and pick up the basketball from the ground with E. Aim at the hoop. Left click to throw. Repeat many times until successful.
This is a throwback achievement to the original Deus Ex where you could play basketball in the very same manner. As far as I can remember, there was a message that showed up when you scored.
In an attempt to hit the basket, try this: position yourself behind the center of the concrete barrier in the back left section of the court. Point straight at the center of the rim, then tilt upwards until you're pointing at the red line around the outside of the backboard. I've be able to consistently make it with this configuration.
As usual in Serious Sam 3, the area in question is in serious plain sight. Acute players will have noticed this small green blinking item in The Power of The Underworld, roughly 400 kills into this serious level (after the serious infinite rocket storage).
It's seriously right under the crosshair. But how the hell would you get up there?
Climb on this seriously damaged wall further ahead, opposite the construction area leading to the next serious part of the map.
From there you'll see serious "secret keys" blinking in serious purple. Go back to the where that green item is located - the serious gates will now open for you.
You'll find a seriously long ladder on your left, before heading through the second gate. Climb it up, and, sure enough...
It's no crash to desktop, but it's a serious sight to behold, plus you get to have a peek on the following serious area. A very good peek I might add, since the green blinking item just around the corner is a serious sniper rifle. Unfortunately, it only comes with 5 serious shots and it appears it only can hold 10 anyway.
Remember to take the ladders on your way down, or you'll simply crash under your serious weight and suffer a seriously humiliating death. You can simply start taking the stairs with E, then jump off them and press E just before reaching the ground serious fast.

So I did a bunch of testing on this tonight. This is what I have found:
The nutshot and the testicle assault do not have to be done on the same enemy. The achievement simply pops after you have done each activity the first time. I killed a gang member via testicular assault without doing a nutshot on him and acquired the achievement.
You need to actually kill the enemy via testicular assault in order to get the achievement. You'll know when you have done this because you'll see a popup for Respect with the name Testicular Manslaughter. Hitting an enemy twice with a testicular assault will get this done.
It does have to be done on a male character. I tried doing testicular assaults on female gang members, and while I was able to kill them and they did the animation, I did not get credit for a Testicular Manslaughter.
