If you mean "punch" as in "hit someone," then just throw a short
punch (mime it, don't actually hit someone -- unless you really mean
it. No, wait. Don't hit anyone. We live in a litigious society.)
If you mean "punch" as in a diabetes inducing beverage then use the
sign for DRINK. So, you could
sign FRUIT DRINK and it would be interpreted as "fruit punch."
If for some strange reason you need to indicate that it is an actual
"fruit drink" (as in a blended fruit drink) you could sign TRUE
FRUIT (as in "real fruit").
DRINK:
The above version is definitely a verb form. (See how the
movement is a bit exaggerated?) To do it as part of the
compound "fruit punch" you do a much smaller, quicker movement
(without the eye gaze).
If you mean "punch" as in "punch a ticket" you should start with a
loose "C"-hand and quickly change it to an "S"-hand then relax the
hand (as if you were holding a hole punch and punched a ticket).
Yes, yes, I know it is complex, but practice a bit and you'll
get it.
