A final tangible reminder of a person for a period of time, delivered to the person leaving (or being left behind) by the first.
"With a huff, she left the room, tipping over the banana tree plant, spilling all of the wet coffee inside all over the floor, a final parting gift for her former girlfriend Stacy."
Someone or something that bites your ankles.
To a postman, an ankle biter is often known as a dog.
To an adult, an ankle biter may be a toddler.
To hikers, an ankle biter is sometimes a tick.
And so on.
