Ruggie will often say ウィッス (uissu), which can be both a laidback greeting and acknowledgement similar to “understood” or “I got it,” very very casual, and he uses it both ways.
Ruggie also ends many of his sentences in ッス, also making his speech more relaxed and casual. He is not the only one, with both Jack and Ace doing so sometimes, but Ruggie is maybe the most well-known for it.
He will also sometimes say “bye bye.”
