A farewell remark
All de best boy! I better do a legger or I'll get an unmerciful root in de hole offa me mudder for bein' late!

Lovely weather for a translation. Would you like me to translate 'All de best' in use for you?
All the very best, old chap! I had better make haste or Mother will deliver a merciless kick to my posterior for my tardiness!
Any good?
