The way I interpret Spamton's [braket text] is that he's sampling phrases from existing media. He can pick out the specific word he wants to sample but can't control the source most of which come from commercials.
Like I legit think Spamton is like a talking EDM song similar to t+pazolite's music

Too many people severely downplay how deep into Denpa and EDM Toby Fox is when he's a 2hufag and Camellia is his go-to music collab partner.
Anyone who listens to lots of EDM(like I do) would clock that Toby Fox's music is really similar in style, that's why UTDR ost is in so many rhythm games!
