Stands for "hot and heavy makeout session," the ultimate weapon in your fooling-around-without-having-sex arsenal. Requires horizontal positioning, and may include dry humping and/or second- or third-bases (but not mouth-to-genital contact, cause that's ho shit).
I really liked him, but it was our first date so I didn't want to bang. We had a sweet HHMS, though.
