しでかす and やらかす difference


Even by looking at a dictionary, I can't make the difference between those two
words しでかす and やらかす... What are the closest english words to translate those
words? Are there situations when one is used and not the other? Is one more
used than the other? (more casual etc.)

Thanks




IMO they are interchangeable, but やらかす is much more common. Some think if you
use やらかす, the speaker is rarely angry, whereas it's more possible that the
speaker is angry if しでかす is used. However, IMO both are archaic and when used,
are used to an almost comical effect & is used rarely in a serious situation.
E.g. one would never say 飲酒運転の車に背骨をおられた。ほんとやからしてくれたわ or
飲酒運転の車に背骨をおられた。ほんとしでかしてくれたわ. It's used for things like
あいつ洗剤全部使って行きよった。やからしてくれたわ。 or あいつ洗剤全部使って行きよった。しでかしてくれたわ。

IMO there is no difference in nuances between the two.
