I checked a few dictionaries and realized that the verb гнать means, in general:
to make something move; to drive sth./sb. out of somewhere (as a transitive verb)
to run fast by vehicle:
гнать на машине
(as an intransitive verb)
But, if I remember correctly, once I heard the sentence "гонит кровь по жилам"
.
I can't find this meaning on any dictionary, but can гнать work as a synonym to течь?
