An Arborphile; one who is sexually aroused by trees.

A stupid person; it refers to the lack of surface area on an individual's brain. The general thought is that the more surface area (wrinkles, creases, etc.) a brain has, the smarter the person is. Conversely, a person with a smooth brain (no wrinkles) has less surface area and would therefore be stupid.

a bird that pecks wood but also is when you tap your erect penis on the girls head while she sucks your balls

A dildo from the 1800's.

When your lady friend is on all fours in the 'doggy' position, you start lapping away at her lady garden with your tongue. The nose starts prodding away at the butthole like a woodpecker at a fresh piece of bark.

Can combine with exhaling sharply once the nose is in. She will then fart out your snot.
Not to be done to any old slut, the Woodpecker is an act of true love.

Quite possibly the most annoying bird there is.

As the chick licks on your nuts, peck her forehead with your dick
