A late night summons -- often made via telephone -- to arrange clandestine bachata dance liaisons on an ad hoc basis.
-OMG girl guess who called me out of the blue late last night wanting to come over my house?
-Who?
-It was jo! Girl I haven't talk to him in weeks, but I let him come over. It was a total bachata call, but it was fun! I learnt so many new steps!
