I'm a big fan of A LOT of couplings. Here's a list of just some of them:
Khunfany- (Nichkhun and Tiffany)
Khunzy-(Nichkhun and Suzy)
Zeddlena- (Zedd and Selena)
Caylor- (Cory M. and Taylor)
Jashley- (Joe and Ashley G.)
Jelena- (Joe and Selena) for some reason I prefer Selena with Joe and not Nick. 
Nemma (?)- (Nicholas H. and Emma W.)
Logemma- (Logan and Emma)
Jogan- (Joe J. and Megan F.)
Lolena- (Logan and Selena)
Shefani- (Gwen and Blake)
And a handful more. I know that's a lot.
