a tangelo is the offspring of a tangerine and an orange. no one knows were the "lo" part came from, but it doesnt matter, because it is there. To recognize a tangelo, you usually find that there is a small rising on the top. it looks like an orange, without the rising.
Tangelo = when an orange and a tangerine have a baby
person 1: Hey man, wan't an orange?
person 2: nah brah, tangelos are whats up.
