A direct translations from the German, referring to tatoos, usually found on (young) women, on their backsides, below the belt line and above the cheeks. They look like the paisly designs of the '70's and remind one of the spread of a 7 point buck. Probably used to the same purpose, too
She' got 17 tattos altogether, the newest of which are those ass antlers peeking out over the tops of her jeans.
A version of the Tramp Stamp tattoo, often a "tribal" design (ironically, worn mostly by white suburban club girls) positioned at the center of the lower back just above the "hipster" panty line, usually forming an "ass arrow" pointing toward the butthole and graphically implying the woman desires anal sex and will rejoice when you follow the sign and enter through the backdoor.
"Her Ass Antlers were so hot, and so was the faux protest and squeal when I followed instructions and buried my fresh breadstick deep in her hot chocolate fondue."
"With my crazy anal fetish, one look at her ass antlers and I knew she was the girl for me"
