The latest video to go viral features a woman caught wearing no underwear when her pants start slipping on a ride in Costa Rica.

The video was captured by an onlooker at the Zapote Festival in San Jose.

The ride throws the passengers from side to side while it spins and jolts. This is when the woman's pants start slipping and the onlookers can be heard on video cheering and whistling.

When the boyfriend realized that the crowd was laughing at her girlfriend and her slipping pants, he does everything to cover up the girl.

Since the boyfriend is still holding to the railing, he uses his legs to hook it around his girlfriend's body to try and cover up her nakedness.

This lasts for 20 humiliating minutes and when the ride comes to an end the woman quickly redresses herself.
