Rots of ruck!
rots of ruck
offensive slang An intentional mispronunciation of "lots of luck" based on the tendency of non-native English speakers from Southeast Asia, especially Japan and China, to conflate the sounds of the letter L and the letter R. My grandfather was always fond of wishing us "rots of ruck" whenever we left his house.
Rots of ruck!(ˈrɑtsəˈrək)
exclam. Lots of luck! (Mocking a Japanese pronunciation.) Have a good trip, and rots of ruck!
