Slang for "I garronTEE", what the gator from the old school TMNT would always say. Such as in this video:

Does not necessarily
mean "I guarantee". Is normally used out of context, such as a replacement for "OK" or "yes".
Paul: Yo man, I just crop dusted his
ass.
Nathan: garron
Nathan: Did you watch that video where the
snake barfs out a hippopotamus?
Paul: garron
