Games : Does Kinzie ever use her safe word ingame in Saints Row?

So Kinzie Kensington mentions in the introduction dialogue for the mission in which you free Zimos that her safe word is "Teacup". I checked the wiki, and the only mention is in her banter with Tanya between missions, after the latter told her she would be a major draw at a brothel.

Is this the only time she uses her safe word, or does she use it at other times as well? I sort-of remember her using it in my playthroughs, and I didn't really bother with homies.
