My Friend Wants to Know (MFWTK) 

It is the most go-to starter phrase when asking an abnormal question to hide behind a facade and save yourself from judgement, embarrassment, humiliation, possibly dishonoring your family's name.

Use this phrase if you are suffering from severe to mild symptoms of curiosity but still want to save your future-self from the consequences of asking such disgraceful questions and from being looked at by other people as a degenerate.

Example 1
Dude 1: Bro, 'my friend wants to know (MFWTK)' if Ron Jeremy's magic beans can REALLY help make your lil jimmy grow bigger and last longer in bed.
Dude 2: (rolling on the floor laughing) HAHAHA!!! Who's the friend?!
Dude 1: (panicking) Shit! I gotta go. I forgot to walk the dog.
Dude 2: Dafuq? But you don't have a dog...

Example 2
Curious Teenager: (asking the users of the interweb) 'MFWTK' how to properly wipe your rear to eliminate dingleberries. He says that he stains his boxers on a daily basis and that his mother is getting tired of cleaning up after his 'shit' like his messy room.
