Dentists need not apply.

The Floss Like a Boss contest at today’s Ole Brook Festival is only for kids and it has nothing to do with dental hygiene.

The Floss is a dance move that involves the dancer repeatedly swinging their arms, with clenched fists, from the back of their body to the front, on each side. It’s popular with the younger crowd, frankly because adults have a hard time trying to master it, said Katie Nations, program director for the Brookhaven-Lincoln County Chamber of Commerce.

The name comes from the moves themselves, which involve a lot of fast arm and hip swings, as though using a huge, invisible piece of dental floss.

The Chamber wants to spotlight the best flosser in town with a contest at noon at the main stage at Ole Brook. Two age categories will be flossing — kids 5 to 8 and 9 to 11 — with the winner of each receiving a plaque.

The stage is set up at Railroad Avenue and Cherokee Street.

It’s free to enter with a Kids Zone armband or a $5 donation to MSGirls4ACure.

The 44th annual Ole Brook Festival kicks off today at 8 a.m. with the MS Girls4ACure and The Pink Sisters’ 10th anniversary 10k and 5k run/walk. An antique car show begins at 10 a.m. and live music and entertainment will continue on the main stage all day. A kids’ zone will open at 9 a.m. with inflatable activities for youngsters. Armbands are $10.

Nations said the festival is full again this year with 175 vendors from all over the Southeast participating.

The Brookhaven Animal Rescue League will have dogs available for petting and adoption and Lincoln County Master Gardeners will be selling a variety of plants.

Nations estimated last year’s festival brought in 10,000 to 12,000 people to the downtown area.

She’s hoping for clear skies, although the National Weather Service in Jackson warns of a chance of showers in Brookhaven between noon and 1 p.m. and possible thunderstorms after 1 p.m. Otherwise, it’s mostly sunny with a high near 87, NWS said.

Whitworth and Railroad avenues between East Chickasaw and East Monticello streets will be reopen at 4 p.m. today.

Cherokee Street between Railroad Avenue and South Jackson Street will also reopen at that time.
