When a person or customer befriends you only to milk IT support (technical support or help desk type activities) from you. Much like a booty call except here the person is just using the other person for technical support and no actual booty or the like is exchanged. In this case it is apparent that the relationship is just to get easy access to technical help when the calls or instant messages always lead to: "Can you fix my printer or my internet is down can you help me?"
Kim: "Hey Carmelo how are you?"
Carmelo: "Hey Kim, I'm fine, how are you?" How was your weekend?"
Kim: "My weekend was fine thank you, but listen i need your help, I can't print and you always fix it faster than anyone else can you help me?"
Carmelo says to self: "why does she only call me to fix her computer problems?"
Johnny: Bro why do you always fall for the IT support booty call, you know she really doesn't like you right?
The next call starts the same way but leads to another IT (no) booty call!
