Half-know 

An individual with whom you have a interesting relationship: This relationship ranges from having seen the pereson now and then, to being meagerly acquainted (as in, having been introduced at one time, say a year ago) with them. Different from an acquaintance, half-knows are often avoided when seen in real life, as meeting with them can be excruciatingly awkward, particularly if the half-know does not recognize you.

Jim: "Hey, Tom, you see that guy over there?"

Tom: "Yeah, what about him?"

Jim: "I've seen him a hundred times at work, but I've never talked to him. Kinda weird, huh?"

Tom: "Don't let him see you; he's a half-know!"

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.
