look up any word, like guncle:
 
1.
Your ideal person. Funny, caring, generous and loving mixed with adventure, sexiness and fun loving. Always smiling and always with the right positive outlook on life. A Sindie always has advice ready and a mix of wit capable of lightening any mood. A person you would want as a friend and who wouldn't let you down. Beautiful outside and in. Someone you can love for a life time.
Guy: You're such a Sindie!
Girl: Aww thanks
