Eh, I ain't mad at em.
It's no different than anime cars, or hot rods with flames, or any other unnecessary but fun for the owner decorations. Not my cup of tea, I draw the line at a maximum of three pieces of auto flair, in the form of placards, stickers, or decals not to exceed a 6×6 area equivalent. That's my personal limit, but I ain't hating anyone trying to find their happy with decorations.
And, tbh, if I had a truck, that motherbumper would have a sexy sasquatch on the rear. All kicked back, chilling. Totally over used, but I still think it's hilariously over the top. Some things just demand to be done, and you can't deny the call of the 'squatch.
