look up any word, like the eiffel tower:
 
1.
A phrase that can be used in place of the more common expression "Right up my street".

This expression has undertones of the word "creek" meaning arse, thus permitting to lower the tone of the conversation with most people not realising.
"I love that track" said Jenny over the loud music at Lyndsey's wedding

to which Dave shouted back "yeah, it's right up my creek"
