Headcanon that Gilan figured out if he talks really fast and says a lot of similar sounding words (ex: Sally sells seashells by the seashore but 10x fast) then Halt, being a non native speaker, gets a little confused for a second while he pieces together what was just said. Gilan now says complete gibberish really fast for no reason to replace or add emphasis to certain words.
Like, instead of saying "Halt, no offense, but your food is horrible" He'll say "Halt, no offense, but your food is dingdangdiddlypiedpicklepiperpositively horrendous" and Halt just stands there for a second debating if he should try and decode that or if he should just give up
