Ya want names, huh? I remember thinking up shipping names for RK pairings once. Hmm. This could be difficult.
(Okay, that one is a joke
Roy/Riza... OfficeShipping? GunShipping sounds good, but that was suggested for Riza/Havoc too.
Havoc/Fury- PuppyShipping. (C'mon! That's gotta work!)
Roy/Riza is generally referred to as RoyAi, right? How about Ai-Shipping?
Envy/Wrath- (Can't quite think of one... I'll try.)
And some random-
Hughes/Gracia- PerfectShipping o(^.^)o
Ed/Psiren- SquishyShipping (XD)
Ed/Russel- Hmm... CloneShipping? Naw. LetterShipping. ('Coz we all know it was a love letter.
Ed/Winry- WrenchShipping <3
