Happy G day!
galactagogue - agent that induces milk secretion
This is a futuristic word. I believe that one day it will mean travelogue to the galaxy.
gimcrack - A cheap and showy object of little or no use; a gewgaw
There seem to be as many words for knickknacks as there are items that carry that description.
gobby - loudmouthed and offensive
If someone called me that, I'd be checking my clothes for a wad of chewing gum.
Come back tomorrow to see if I raise some H.
