A game where a wheel is spun with two options: slings, and spoons. If the wheel lands on slings then ur testicles will be surgically removed and then slung onto ur face. If it lands in your mouth you must eat it, if it hits your eye your eye is replaced with your testicle. If the wheel lands on spoon then ur testicles are violently carved out with just a regular spoon and then force fed to you.
When a male has sweaty testicles and pelvis thrust forward and backward causing his sweaty testicles to make a “slapping” noise. Preferably done right out of the shower in only a towel.
Sam walked out of the shower in a towel with a crazed look in his eyes, and moved his hips back and forth rapidly creating a loud slapping noise. He was performing a powerful swingset.
“It stings in the shower” refers to mental health and thoughts that you may have pushed away become more vivid in the shower, and clearer to remember. It also referrers to the fact that depression can be stronger in the shower, and that self-harm provoking words will “sting”.
Another interpretation is that if you have recently self-harmed (cut yourself) the shower water may sting it. That is also what it could mean.
