“There’s something stuck between your … tweets”: The Twitter campaign for a new toothbrush from Colgate, which ran for just a
limited period, encouraged users to discreetly “tweet” (point) out to people that they had bits of food stuck between their teeth.

Nir Refuah: “A new low-budget social media campaign from Colgate which anonymously alerts people to food stuck in their teeth.
The user chooses a friend, and the friend receives an anonymous message – ‘A friend asked me to tell you there’s something stuck
in your teeth’ – together with a coupon link.”
