Alaskan Christmas Tree

When several (at least 3) males gather in an outward-facing circle, strip down their clothes, and lean down onto their hands and knees with their anuses raised skyward. Baubles can be hung on their peners however this was a modern addition and is not necessary for a true Alaskan Christmas Tree

Cathy: "Oh my god, Andrew told me he and his friends were gonna do an Alaskan Christmas Tree this year"
Anna: "Ohhh damn girl, I didn't know he was a homie-sexual"
