<human>: Can you provide a brief rundown of the text in within 3 sentences?

Me (M-19) her (F-19) met this girl at a party...forgot about her then got her instagram a couples days later then maybe 2 weeks later messaged her this:

Me:Heyy whats upp 😄 do remember me?
Her:Hi, yeah I do (: we met at Kevin's right?
Me:Yeaah correct lol im with kevin right now and we were just talking about the party and you just kind of popped up in my head even though we only talked for like half a seconds so i just figured i'd say whats up!!!
Her:Awwwh tell him I say "hi snoopy!!" LOL oh thats nice. Yeah we barely talked! How are you tho? Did you manage to wash that beer out of your pants 😂
Me:Lol snoopy ahah that funny im gonna clown him on that name lol.... Im doin good kinda lol and honestly i think there a permanent scent of beer soaked in the pants.
Me:do you go to uni or college? 

She responded almost immediately after each msg then she just stopped...the msg where sent on IG and she been on it since. So now my question is what should i say after since she hasn't responded in a couple of days
<bot>: msg a girl talked for 5 min then she stopped responding...3 days later I'm trying to figure what i should say to her?
