Porn Star Lisa Ann -- I'm Dating the OK State Fan Who Mocked My Lady Holes

The college kid who made a game sign poking fun at porn star Lisa Ann's lady bits is now officially the luckiest guy in the universe ... 'cause Lisa just booked him for a date live on TMZ Sports.

OK State student -- Matt McGann -- made the sign for last weekend's home game against Baylor and it was awesome. It read, “Baylor’s defense has more holes to fill than Lisa Ann.”

Now the even awesomer part. Lisa saw that sign ... and not only was she not offended, she found the zinger so hilarious she invited Matt to be her guest of honor to the AVN Porn Awards.

Matt (obviously) accepted the offer ... and it all went down on the show.

It's pretty unbelievable. You gotta see this.
