Ketchup on tacos ... psycho move or delicious topping?!?!
Former MLB star Adam Jones is clearly all for it ... 'cause the dude loaded up his Cinco De Mayo tacos with the red stuff -- and had no shame about it!!!
Jones posted the pic Tuesday ... showing off some soft shell delight smothered in Heinz magic.
The problem??? Some people think that's a borderline criminal offense ... and the 34-year-old even got hate in the comments over it!!
"I know that’s not ketchup on your taco...." one fan wrote. "your SD card’s gonna get pulled if so.
