Scavenged from the interwebtubenets..
You asked what one would be doing if one were simply to mong. Well, there is such a verb, and we’ve had it since Anglo-Saxon days.
"The verb “mong,” according to the OED, means to barter or trade in something, chiefly to trade or spread gossip, rumors, and so on.
We don’t see it much these days, and when we do, it’s often used in a comical way, as in this 1949 example from Ogden Nash: “These editorial scandalmongers have to mong scandal.”
