Mirroring hmv
pmv
A music video where porn scenes are edited together and synchronized to the beat.
I went through multiple sources and found similar descriptions to the ones that @Falafel has added to the Wiki. It appears that there was no consensus on the duration of a fap-hero like I though there was.
So my recommendation follows the logic with FH/HMV and CH/PMV with their respective pair.
A Fap Hero requires a beatbar synced to the music or beat.
Without a beat bar, it would classify as an HMV
Fap Hero(s) with multiple rounds should then receive a different tag to not overlap with HMV
compilation is in the wiki and matches the description
