なんでよ -  Nande yo (meaning "why" but more demanding/ aggressive/ exclamatory lol)

ちょと 待って - Cho to matte (wait a minute/ wait a little)/  待って待って待って -  matte, matte, matte (wait, wait, wait)

バカ ウザイ -  Baka uzai (stupid and annoy/ stupid dumb@$$, don't typically see it used much but was one of the first japanese insults I learned)

死ね  - shine/ shin (die/ go die)

ですか - Desu ka (are you?/ is it? I usually see it in the context of "are you for real/ being serious")

本当に - Hontoni (really?)

俺 - Ore/  私 - Watashi (both mean "I")

additionally, it barely counts but I love the honorific "-kun"
