Don’t know about you, but when I started yoyoing there were a lot of abbreviations that I didn’t understand. This thread should help all the new guys. If there’s something I missed, feel free to post it.
YYE-YoyoExpert
YYN-YoyoNation
YYF-YoyoFactory
YYJ-YoyoJam
FHZ-Freehand Zero
MFHZ-Metal Zero
Poly-Polyester
PGM-Plastic Grind Machine
DM-Dark Magic
CLYW-Caribou Lodge Yoyo Works
FH-Freehand
FH2-Freehand two
FH0-Alternate Freehand zero for abbreviation…
GM2-YoYoFactory Grind Machine 2
X-Con- This is weird because it used to be a yoyo, but then was discontinued and replaced with the X-ConVict, which is abbreviated X-Con
Aqua-Aquarious
FHC-Freehand Cyclon
Actually, I would say the abbreviation for X-ConVict would be either X-Vict or just Vict. X-Con definitely refers to a totally different yoyo
TH - throwhand (hand yoyo is attached to)
NTH - nonthrowhand (hand yoyo isn’t attached to)
This should be sticked. It seems really helpful.
YYR=YoYoRecreation.
YYG=YoYoGuy.
SPYY=Saturn Precision YoYos.
BK=Buddah King or more commenly Black Knight.

PS=Protostar.
HM=Hitman.
NB=New Breed.
BAC=Bay Area Classic yoyo contest.
BLC=Bill Lebowitz Classic yoyo contest.
NYYC=National YoYo Contest. Usually referes to the U.S. contest. Most other contries are noted with another initial at the beggining( i.e. ENYYC, PNYYE).
ENYYC=European National YoYo Contest.
PNYYE=Phillapian National YoYo Contest.
WYYC=World YoYo Contest.

Also there’s a thread similar to this

This thread should help even though it states only brands
