To be unabashed is to be unembarrassed. When you're unabashed, you're confident and proud. You're letting it all hang out.
Unabashed describes how good you feel about something. If you're an unabashed Red Sox fan, you're a proud Red Sox fan. If you're an unabashed patriot, you totally love your country — and wear clothing featuring bald eagles and the American flag. This word is the opposite of abashed, which means embarrassed. If you feel bad about something, then you really can't be unabashed.
