When you get an anime reference for the first time lolz

So on the anime "that time I got reincarnated as a slime" the main slime on that anime makes slime references at the end of his sentences to see if people from his world get them. He says, "I'm a good slime,*sluuuurrrp*". And this game I'm playing called 'dragon quest builders 2' the slimes say that. Could I have just found a Japanese anime reference?
