Note that in Spain "coger" also means "to grab or hold" just like in Colombia. So most dictionaries are likely to use that.
But you are completely right.
I mean, "una polla" in Spain would be "a penis"... but everywhere else it means either "a female chicken" or, in some places, "a girlfriend". In others it means "a bet", and I think in Mexico it's the name of an egg-based drink.
