Know both girls from Tinder, talked to them like a week ago. Innitated contact today

Girl 1:

me: you actually ever visit my city?

her: yes, for school everyday actually haha

me: well let's grab coffee next week (trying to go from coffee to a bar nearby)

her: Can't, i'm in London next week

me: oeh nice

Okay, so i just left it at that. Didn't know what to do or what to say, i thought 'oeh nice' was good enough

Girl 2:

me: hey lets grab coffee next week

her: why

Obviously a shit-test (i think i'm getting better at recognizing them), the moment she said this i was like: wow, this is some wannabe high-class uptight bitch so i actually went troll-mode

me: because i like to put three fingers in my ass and i want you to watch

her: do you think you're funny?

me: My mother thinks i am

The last one was five minutes ago, she can still respond, But i dont think so. Feedback much appreciated
