Spoofing

[Sarah]

The word spoof means to hoax, trick, or deceive. Therefore, in the IT world, spoofing refers tricking or deceiving computer systems or other computer users. This is typically done by hiding ones identity or faking the identity of another user on the Internet.
Spoofing can take place on the Internet in several different ways. One common method is through e-mail. E-mail spoofing involves sending messages from a bogus e-mail address or faking the e-mail address of another user. Fortunately, most e-mail servers have security features that prevent unauthorized users from sending messages. However, spammers often send spam messages from their own SMTP, which allows them to use fake e-mail addresses. Therefore, it is possible to receive e-mail from an address that is not the actual address of the person sending the message.
Another way spoofing takes place on the Internet is via IP spoofing. This involves masking the IP address of a certain computer system. By hiding or faking a computers IP address, it is difficult for other systems to determine where the computer is transmitting data from. Because IP spoofing makes it difficult to track the source of a transmission, it is often used in denial-of-service attacks that overload a server. This may cause the server to either crash or become unresponsive to legitimate requests. Fortunately, software security systems have been developed that can identify denial-of-service attacks and block their transmissions.
Finally, spoofing can be done by simply faking an identity, such as an online username. For example, when posting on an Web discussion board, a user may pretend he is the representative for a certain company, when he actually has no association with the organization. In online chat rooms, users may fake their age, gender, and location.
While the Internet is a great place to communicate with others, it can also be an easy place to fake an identity. Therefore, always make sure you know who you are communicating with before giving out private information.

[Cami]

An oral sex act most commonly performed on males in which the erect penis is taken into the mouth, a hard vacuum or [suction] is created, and then the penis is promptly removed, causing an audible inrush of air. Release of [the vacuum] and continued intake of air by the performer allows air to rush over the [penile] [glans], eliciting unsuspected pleasure. Often compared to the feeling of blowing on the tip of a penis, but can be performed in a single fluid movement, and is easily repeatable. For best results the lips should not immediately purse upon penile removal. Care must be taken to not engage too much suction upon the penis as damage could potentially occur.
The female version is similar, except the exposed glans of the [clitoral] shaft is taken into the performers mouth, and then removed. Most find they must pop their lips off the clitoris, as there is not much to actually wrap lips around.
