When you pour your
tea from the teapot after it has steeped & it’s only hot
water.
Usually because you didn’t actually put a teabag in but thought you had. Sometimes happens when your kid steals the teabag for their
tea thinking it’s funny.
“Man, it’s way too early for this. My toasted English muffin was about to pop up & I go to pour my
tea from the teapot & it was nothing but a ghost
tea.”
You thought it was there but it’s not, just like a ghost. Only hot
water.
