Hmm, your opinions on this chat? Did I annoy him or is he being touchy?

[MartinaFranklyn]

Had a chat with my BF about what I bought whilst shopping, did I offend him? We're talking about my new dress:

Me:
i'd wear it to your partay but cannae come :'(
partaying in yorkshire instead

Him:
you can wear it to my 18th

Me:
cool
i might be a little overdressed tho
its quite posh

Him:
hey, I'll be in a kilt

Me:
ok then thats ok
or should i wear my mini kilt?

Him:
upto you
I changed my name
yay

Me:
why?

him:
Fancied a change

Me:
cool

(a few minutes pass)

Me:
sorry for ignoring you btw was prancing around in my new dress

Him:
I could change mine to Karate king
coz I am the karate king

Me:
should i wear my killer heels to your party or will it make you feel short
Cause they make me mahoosive

him:
FOR THE LAST TIME UPTO YOU

me:
was just brainstorming dude

Him:
grrrrrrr

Me:
you know, bouncing ideas around, creating magic

Him:
ok

me:
binary fission and all that

him:
ok


Then he went offline I think maybe he was mad cause he's touchy about his height cause I'm a bit taller than him. I was just trying to lighten the mood with 'binary fission and all that'

What should I do?
I edited out a bit after the 'karate king' bit cause we were talking about names for ages
