We're glad you asked. Froth Cone Fever is a condition where one's froth cones become too frothy. It's like a cold, but not really.
Symptoms include: excessive frothiness, cone-shaped lesions, and an unrelenting desire to froth more.
We recommend a strict regimen of calmness, hydration, and avoidance of any activities that might exacerbate the condition. Oh, and also, take more froth cones.
No, no, no. We're not sure how that works, but we're pretty sure it's not contagious. Maybe. Possibly. Don't ask us, we're not experts.
There's no cure, but there's a support group. It's called the "Froth Cone Fever Survivors Anonymous" and it meets every Thursday at the local coffee shop. Be there!
