1) Your best male friend
Derived from the word Wifey
Instead of calling him your 'Wifey', which would be kind of weird you'd call him your 'Maifey'
Maifey's are the BEST male friend a girl could ever have. They can never be replaced so be selective with who you call your maifey.
2) My maifey is hotter then yours.
3) Maifey for lifey!
