top cola

why is it called a top cola. or others called cola? is it an abreviation for a larger word? sorry just curiouse i cant anything on google about it.

A cola or "bud site" is the part of a female cannabis plant where the flowers or buds grow together tightly. Healthy plants usually form one main cola from the center of the branching structure with smaller colas forming around the outside of the plant. Training and trimming techniques (like LST, ScrOG, FIMing and topping) can be used to increase the amount of large colas that a plant will form.

found this but it says nothing about how the name came about. im wondering if it has something to do with cola cans mayby.
