a word used by two people in love that are too nervous at the moment they want to say "i love you" to actually say it. they will instead say "i lo you" which implies their true feelings without setting themselves up for rejection of rushing things. a good marker for knowing where you are in your relationship and seeing how you're halfway there to love.

*most likely followed a week later with the phrase "i lov you" and then sometime later the full phrase "i love you"*
girl: we need a new term. i'm tired of saying how much i like you.
boy: agreed........... what about lo?
girl: lo?
boy: yeah, lo. it means we're halfway there to...... that other word.
girl: i like it. i lo you.
boy: i lo you too.
