A way to tell a significant other you love them, but in a more subtle and sweet way. Constructed by merging the words 'love you' together. Can also be written with any amount of Os, e.g. 'Lyoooo'.

The word "Lyoo" is short for "love you". If you are in a hurry and for some reason can't say "I love you" fast enough to your lover, then you can say "lyoo".
