They only do it after something sugary.
Not seen that before but there is a horse on out yard that almost windsucks. He put his head in and gulps air almost like if he was using a fence or door but isn't!
It's an oral stereotypy, just like windsucking or cribbing (but because it doesn't cause any damage people think it's funny or cute). It seems to be linked to digestive discomfort... people say their horse does it "after eating" - but I have yet to see a horse do it after eating grass, hay or haylage. They only do it after something sugary. Abruptly weaned foals do seem more likely to do it - but only because they're also more likely to have digestive problems.
Have one that does similar at the stud I work at. She sticks her tongue out a little though.
She was a hand reared foal.
