colear

To wag (a tail): el perro coleaba de alegría. In Mexico, andar coleando or the noun coleo also refers to a rodeo sport where a rider grabs a bull's tail to trip it. The figurative expression el asunto todavía colea means a matter is still ongoing or unresolved.

• El perro coleaba emocionado al verla llegar. — The dog wagged its tail excitedly when it saw her arrive.
• El escándalo político todavía colea meses después. — The political scandal is still dragging on months later.
• En algunos rodeos mexicanos se practica el coleo de toros. — In some Mexican rodeos, bull-tailing is practiced.

The figurative sense (algo todavía colea, meaning an issue is still unresolved) is common in news writing — don't read it literally as an animal wagging its tail in that context.
