Donghae 

This is something closer to "weeb slang."

Donghae is a name for the "East Sea" or "Sea of Japan." It's a body of water that essentially connects the two countries (that historically don't get along).

Hence: Donghae (when used in weeb slang) means "After a slow burn (a long waiting period) your OTP finally get together." It's meant to be used as more of a sound effect or to punctuate.

Weeb 1: IT TOOK ED 64 EPISODES TO GET WITH WINRY! FUCK! WE'RE FINALLY HERE!
Weeb 2: DONGHAE!!!
