Soaking = wet

The boys have a new saying. It's "soaking." They say it for everything. Let me explain.
If they're hot, they say, "It's soaking hot outside."
If they're hungry, they say, "I'm soaking hungry!"
If they're tired...(yeah right)...they say, "I'm soaking tired!"
I keep trying to explain to them that soaking means wet, but to no avail...they keep using it in their terms. It sure is funny.
