Glomp
v, to glomp
NOT sexual, it is the action of one person lovingly (and dramatically) attacking another with a hug.
A glomp is often preadatory and lies somewhere in the grey area between a caring embrace, and a flying leap to tackle someone.
The term is used extesively in anime culture, as well as online in text form (anime because many anime characters do this often, and online because it is short and descriptive).
real life:
A runs at B as if to bowl her over, but instead picks up B and spins her around while squeezing her tightly.
online:
-*glomp!*
=hi!.. *squeek!* cant breathe ^-^
-*loosens grip*
