When you meet someone in an MMO (preferably of the opposite sex), talk to them every day for 2 years, then finally meet in real life and "seal your love". You have successfully become "the love sealer".

NOTE: Said long distance love might only last about 3-4 months because online acquaintances are limited to... your ingame avatar. Otherwise, you'll constantly be at each other's throats about real couple's issues.
Armand: I can't believe you let that guy sleep with you before you gave me a chance to be the love sealer.
Jenesse: You're a fucking idiot.
