First of all "YTP" is short for "Youtube Poop".
YTPs are usally 1-2 minutes long but usaually leave you wanting it to last forever (until you can't breathe)
"YTPMV" is short for "Youtube Poop Music Video"
They are what they imply,
How to make a simple YTP:
1. Find source
2. Get editing program
and last but not least
4. Waste an entire day putting you ideas into reality.
and I only made this for badges.
