You may have heard a man say "You can get the business," meaning he'd readily have sex with you. Don't get too excited. Depending on which words he emphasizes, as well as a choice grammatical substitution, the compliment has two meanings.
"You can get the business (this will sound like 'biz-ness')!": He wants you, needs you, has to have you, because getting with you would be like winning the World Series... of poker. [Listen for the exclamation point.]
"You can (or, mostly likely, 'could') get the business.": He wouldn't need a gun pressed to his head to get with you, but he'd rather look elsewhere before settling.
