1.
An incredibly attractive and amazing young man. Contrary to most definitions, he is selfless and generous; a kind and gentle soul. Any woman would be extremely lucky to have Tancredi as their significant other. Although a flirt, he is always sincere in his compliments, despite the receivers denying. He would rather put his friends and loved one's happiness before his own, which speaks wonders about his chivalry and benevolence. He deserves to be treated right with love and kindness.
"Wow, that guy is incredible"
"Yeah, he's a Tancredi"

2.
A person with a generally sour dispostion. Has a great dislike for all people especially outside of ones race. If the tancredi is a ginger they tend to be slightly angrier.
Tedd : Hey look at that tancredi scowl
