When you are dating/ in a relationship with a woman who is VERY fat and much larger than yourself. What you do is hug, chalk off the ending of your arms, and then move on to the next gap that is not hug and hug and chalk again.
This can also be used when you have a mother who is bigger than the children, and the child wants to hug her.
(From the Hoagy Carmichael song- Huggin' and Chalkin')
Dude, your girl is so fat, that you are hugging and chalking just to show her some love.
