Daddy Yankee
just got a bitch-slappin' in court ... the Reggaeton star has been ordered to pay $6,000,000 to a promoter who says his EYES BLED after DY bailed out of a major concert tour.

Yankee -- aka Ramón Luis Ayala Rodríguez -- was sued in Florida back in 2011 after he pulled the plug on a 10-city tour in Argentina two days before the first show.

The concert promoter -- Diego Hernan De Iraola -- says he got screwed out of $820,000 that he paid Yankee up front ... and suffered pain and embarrassment.  He says the stress even caused his eyes to bleed ... so he sued for damages and won.

We reached out to Yankee's people for comment -- so far, no word back.
