dive

I'm a little stuck... Click here to teach me more about this clue!

'seedy joint' is the definition.
(I've seen this in another clue)

I cannot understand how the rest of the clue works.

(Other definitions for dive that I've seen before include "Plunge head first" , "Disreputable establishment" , "Leap into water" , "Low establishment" , "Headlong plunge into water" .)

I've seen this clue in The Guardian.
