A hug in the manner of a small child, similar to a bearhug but often including one or both legs as well as arms. Also a hug in which the hugger jumps and catches the victim by surprise or off-guard. Occasionally referred to as a cross between a running tackle and a bearhug.
A charges at B while B is unaware and body-slams them spread-eagle and latches onto them with all four limbs! B screams in surprise and gasps for air. Realizing it was not an attack, B hugs A back. :3
