MLB Announcer -- Sorority Girl Shaming ... Over Selfies at Baseball Game (VIDEO)

An MLB announcer LOST IT on a bunch of Arizona State sorority girls Wednesday night ... when he noticed they were more obsessed with taking hot dog selfies than watching the game -- and it was HILARIOUS!!

Ya gotta watch the clip ... the announcers just clown on the group of Alpha Chi Omegas who take selfie after selfie after selfie ... using various food items as props, including a churro.

At one point the announcer asks ... "Do you have to make faces when you take selfies?"

Yes.

BTW, the girls don't seem upset -- in fact, they bragged about it on the official AXO twitter account ... and even posted a pic of the hot dog selfie.
