Hi guys, i was wondering does anyone know how to do a reverse lookup for a word?

i have a definition for a word but can't find the word itself :-)

last week we were on holiday in brisbane and on one of the water taxis there a word and ir's definition was playing amongst the advertisments for air conditioners etc. my wife was particularly taken with the one word description of a vague walk, but now neither of us can remember the actual word.

it ended in ate [like perambulate] but that's about all we can remember

i've tried online dictionaries to figure the word from the definition, but so far nothing has been found, maybe you can help?
