KISS-FIST is a very common ASL sign that means "love." However, this is different from the sign LOVE in that KISS-FIST is normally used to mean "love something" instead of "love someone." For example, you might sign, "t(MYFATHER) KISS-FIST HISCAR" to
mean "My dad loves his car."
To make the KISS-FIST, sign you just kiss the back of the fist of your dominant hand and move it slightly and quickly away from your face.
