Booty Call
Booty Call is an activity in The Ballad of Gay Tony. Luis can dance with girls in Maisonette 9 and if he does well they'll bring Luis to the restrooms for an encounter, after which they may give Luis their number. Afterwards, they can be contacted, or may contact Luis, for a "booty call." After the arrangement, the girl's home will be represented by a pair of buttocks icon in the radar. Booty calls are optional and appear to have no impact on the game and are not necessary for 100% completion, however the trophy/achievement Warm Coffee is rewarded the first time a booty call is undertaken, unless the trophy had previously been awarded in the main GTA IV game.
