If something is Flantastic it is extremely jewish, sticky, and dirty. A flantastic item would be something like a used uncleaned double-dong and doing a flanstastic deed would be like giving yourself or another person the reverse shocker.
If someone is called flantastic it means they are easy, slutty, and/or dirty.
