Meme Guitar Riff for FAFO

Hi, I can't remember what song is played whenever there's a FAFO meme. It's usually played when something unexpected happened and the video gets paused and then that guitar riff gets played.

It's not Jojo's "To be continued" guitar riff. It's goes like a long strum first for like 3 seconds and then followed by a higher note strum and then descending - duuuuuuuun, duun duuuun dun.
