obviously some of these are the same grab sort of but different tricks contextually...
melon, lien, method, nose, crail, madonna, frigid air, rocket air, mute, slob, japan, indy, tuck knee, stiffy, tail, seatbealt, stalefish, benihana, grossman, roastbeef, cannonball, dogpiss but i guess you could take a foot off almost all of them.
one thing i've never seen is like the opposite of those grossman/roastbeef type grabs, where say you were almost grabbing melon but then you stuck your front hand through your legs from the back and grabbed mute, or went to grab stalefish but went through your legs and grabbed indy. or i guess the crail and seatbelt concepts done behind the body instead of in front. would be undoubtedly ghastly but that's about all i can think of in terms other options.
