B-flip
a thong that's so tiny it looks like it was made by a kid with no idea what a thong is and it's either for swimming or wearing under clothes and it's definitely not for people who don't want everyone to see their butt
My sister wore a B-flip to the pool and everyone saw her butt
My uncle wore a B-flip to work and his boss was confused
My cousin's B-flip fell off during a dance and it was awkward
