Immoral (definition): Obsolete expression meaning "politically incorrect". - Richard Summerbell

Erotica: the depiction of naked men. Depictions of naked women are far less innocent and are known as "pornography".

Butch (definition): Macho with a purse.

You are a mystery in an enigma in a big ball of fur,
An irresistible magnet to every child and flea and burr.
Your nose is high-resolution while I live in a near-scentless fog
You run at high speed, while I just have to slog (but it's a good ol' slog)
So I just want to thank you for being my dog....
