In the recent video he made where he played Butt Sniffin Pugs with Marzia, video link is here,
at around 0:24 and also 6:20, the song played twice.
Couldn't find the song anywhere. Shazam didn't work neither did Google.
If you guys have any clue, please let me know. Thanks

you can listen to it here on youtube. it really doesn't show up anywhere, but someone on reddit found it after being set off on a lyrical goose chase by pewdie.
