Typically a Christmas Orange refer to a Chinese Mandarin orange, but may also be Japanese Mandarin orange that becomes a popular buy at Christmastime. Often they are sold in 5 pound boxes full of individually wrapped oranges.

The taste of said oranges is sweet and juicy. They are delicious.
I wish it was Christmas all year round so we could eat more Christmas Oranges.

Get the Christmas Orange mug.
The taste experienced when taking a hit from a clean vaporizer with a freshly packed bowl of marijuana.
John: Hey Mike, hit this vape I just loaded it
Mike: Mmm, that taste so good, completely different than smoking
John: Yea, that is the sweet taste of Orange Christmas
Mike: Amen!
