Viewed sideways becomes a heart. Usually used to express luv or love for something over the internet. Can be used on a complete stranger you met in an online forum. Less creepy than using the word love on people you don't know.
note: <3 (luv) and love are not necesarily the same. Luv, like 'lub', is a less serious and more lighthearted version of 'love'.
I <3 u = I luv u = I lubu
(none of these is equal to 'I love you')
