A cleverly derived synonym for phone sex.
Gal B: So did she end up going to his house?
Gal A: No! Now, all she does is sit in her bedroom and phonicates with him for hours....while I'm in the room!!
Gal B: You know, I was never a huge fan of phone sex....too many awkward silences.
Gal A: Yeah...I definitely prefer actual sex to phonication.
