Straight lesbians don't exist. A lesbian is attracted to women and women only. If you are attrackted to anything other than women, chances are you're bisexual, pansexual, polysexual etc. The term also invalidates the lesbian community and the bisexual/pansexual community.

The act of extreme masturbation. You must "knock one out" whilst in close proximity to any of the following; Your mum, a nun, your boss, a member of parliament, George Michael. A person with capabilities to act upon catching you mid self-abuse obvisouly ups the ante. Ejaculation must be reached before your danger wank target comes (no pun intended) to investigate. The higher the chances of being discovered with one's pants down, pulling one's war face is obviously where the danger comes from. The more danger involved the harder (or softer) it is to complete the task in hand (snigger). The more dangerous the better. The chance of being arrested, pummeled by an angry father or having your hand severed by an arab's sabre means that you are a pro "Danger wanker."

Straight Lesbianism (a definition): a state of mind compelled by the depleting image of lesbians living in metropolitan areas (i.e . Miami). This state of mind, though oxymoronic in nature, serves as a gateway for higher echelon lesbians to fluctuate between the heterosexual social scene and homosexual love affairs. Straight lesbians mend the vital resources of both worlds and in a paradoxical state purposed to establish a strong repertoire for future generations of straight lesbians...
