With an ass like that you gotta blow ... thousands and THOUSANDS of dollars at an Atlanta strip club -- at least that's what Ludacris did this week ... and we got pics.

Luda hit up Diamonds of ATL on Wednesday night for some much-needed rainmaking -- along with DJ Infamous, Luda's girlfriend Eudoxie, singer Monica, and rapper Lil Scrappy.

According to sources, Luda dropped in excess of $10,000 the entire night. (Not bad ... but not Fabolous either.)

No question -- these chicks do stuff your chicks wish they could.
