Tock

People typically tock at night. This is when two people lock their toes together, typically in bed. It would be the equivalent of holding hands but you are holding feet.

Last night Kya said to me we need to "tock". I asked "about what" and she said no this is where we lay in bed, lock toes and hold feet in a display of love and romance. Just like holding hands walking down the street, we will hold feet all night long with a tock.
