The name used within gangs when refering or talking to one another.The word is a mixture of the wordsgang and family.So you would only refer to a Real Friend as 'fangle'. Can also be used as a greeting or farewell within the gang.
That angle you look fattest at. Can be used positively or negatively.
Ol: "Babe look if i have the phone down on the floor pointing up at my but at sixty degrees, my otherwise skinnybutt looks so juicy. This really is my fangle."
