Posting a sign asking for a hug, then sobbing uncontrollably during the hug; these hugs usually end in arrest(even by loved ones).

Goes by many monikers. i.e. Awkward Lock; Pelvic Press.

When a dude goes in for the hug, but sneaks in a little pelvic thrust/hip grind action on a girls lower abdomen. Leading to a very one-sided uncomfortable pause. Guys don't usually know they do it.
