Here's one I have had a lot of success with.
I start by typing jibberish: lkjsdhflkjsdlfkjds
If they are adventurous and spontaneous they will respond with more jibberish
If they are more reserved, they may react with hesitation like, "Ok?" or "LOL what?"
I usually will respond either way with another "kjsldkjdlfkjdlfkjd"
If they are cool and respond with more jibberish, i do it one more time and put a question mark in, "skdjkjfhouidoifhik??"
Then after their next response, I say something like, "Realllllllly??! You are more dirty than I thought you were
" or "Dammnnnnn girl maybe later"
Inferring the jibberish was some language I have only with her and it can be whatever I want. If she doesn't go along with it and asks "what?" I say, "It's the language I invented for only you and me to know
" Making her feel special.
I always use it again the next time if they played along and then after that I don't use it anymore. It could easily be overused.
I have also used it to quickly make a connection with a girl if i don't have much time to talk but i want to get her number or let her know im going to be having a longer conversation with her later. I will go through the routine, and then as soon as it gets sexual i say something to encourage a catstring like, "Well maybe you will get your dirty wish
then right after, "i gotta go but i will follow up on your little fantasy over text" get the number quick if I don't have it.
There are obviously other directions you can go with this one so have fun with it. If anyone has ways to make it better let me know!
