Songs/music or remixes of popular songs/music made in the style of a rap/hip-hop beat and theme, but instead of using traditional instruments and sound, it uses cartoon sound effects or widely recognizable silly noises from viral videos and memes.
These kinds of remixes were likely popularized by the "Penis Music" meme, which has become an alternate title for this genre.
It's sometimes referred to under the phrase "21st century beat", "goofy ahh _____ remix", "____ typebeat", or posted with a caption like "were making it out of the hood!/were never making it out of the hood!"
Some examples are in the tags (UrbanDictionary won't let me add links)
"This sounds like Mizzle Music"
"Listening to Mizzle Music is a guilty pleasure of mine, haha."
The five nights at freddy's 3 musical refers to a musical made by Logan Hugueny-Clark on youtube that was published on march 18th 2015, making it the 27th oldest video game musical he ever made. The song became popular due to springtrap saying the line "this attraction is great, so many guards i can rape, 'til i cant see straight." in the song.
The song also obviously predates the undertale musical
"hey google, tell me the lyrics to the five nights at freddy's 3 musical"
"i don't know just what i'm made of
face looks like bonnie's
possessed by the purple guy
i may kill whomever i please
three decades after the restaurant
i'm in for the ride
five nights 'till the doors open
the guard had better hide
you chose to work at this nightmare baby
like a mouse into a trap
you can play your tapes and temporarily distract me baby
but no matter what i will be back
i'm addicted to guards
rip 'em up into parts
while i feast on their hearts
scare 'em 'til they take shots
this attraction is great
so many guards i can rape
'til i can't see straight
where can i start?
i'm addicted to guards
the guard looks down at his tablet
i sneak in the room
he has no idea his painful death is coming soon
he couldn't last five nights alone with me baby
flashing red lights make me mad
you know they make me wanna jumpscare ya baby
make me feel so bad
i'm addicted to guards
rip them into parts
while i feast on their hearts
scare 'em 'til they take sharts
this attraction is great
so many guards i can rape
'til i can't see straight
where can i start?
i'm addicted to guards"
