Banana cake is a term used to describe all forms of sex that are not 'physically' relevant, such as Phone-sex/Cyber-sex.

It is often used as a term to describe ones affections for another on social networking sites such as facebook, twitter, and other public forums.

Banana cake is performed when those involved are aware that they are not likely to ever meet in real life, but wish to consumate a mutual desire for heightened intimacy involving the release of bodily fluids via talking on the phone, texting, msn, as well as on social networking sites.
Actual exchange on Windows live messenger/MSN:

Dee: Higz, last nights banana cake was mind blowing, I'm still quivering thinking about it. God! I am so wet!

Higz: Yes, it certainly was, but when are we going to meet up for the real deal? We're in the same city ffs, so what about it muffin ass?

Dee: Maybe I'll pay you a surprise visit on your bday <3

Higz: That's what you said back in 08. If you're setting up for another argument, I'm not falling for it. Arguing makes you horny, and to be quite honest.. banana cake just doesn't cut it anymore with me.

Dee: In other words, you are saying that you are undressed and Gung-ho for another round of banana cake until your bday arrives?

Higz: Hmmm.. pretty much. Okay, I'm laying blindfolded on my workout bench, and you walk in wearing nothing. Over to you....

Dee: Now you're talking baby!
