look up any word, like bootylicious:
1. Romione
the couple name of Ron Weasley & Hermione Granger.
ROn + HerMIONE = Romione.

Mostly used on tumblr from hardcore shippers such as myself.
"Who is your OTP in Harry Potter?"
"Romione!"
2. romione
The ship name for Ron Weasley and Hermione Granger in J.K. Rowling's Harry Potter franchise.
SPOILER ALERT: This ship ends up together at the end of the series, and married in the epilogue. They have a son and daughter: Rose and Hugo Weasley.
HPer 1: I'm such a dromione fan. Will never stop reading those ships.
HPer 2: How can you not be a romione? OTP FOR LIFE.
