1 definition by Pahoehoe

To contribute money for a specific purpose or for the good of the group. Informal

The phrase may derive from the act of passing around a hat, into which contributors would "throw in" some money.
"Another six-pack of Hamm's? I'll throw in for that!"

Not: "There's orphans starving in Haiti? I'll throw in for that!" Situation too formal or grave.
