Loony BoB - told me to calm down
Baloki - I made kissing/budgie noises, he meowed.
Female Ryuichi - Breathed heavily until she hung up.
Pure Strife - I got an answerphone, spoke like an Eastern European and stated that I loved him. (Actually, I remembered that I once got an answer and I think we yelled "YOUR MUM!" at each other)

People who I have texted that weren't mentioned above:
Levian - Involved giraffes
Xander - way too many times, I should phone her and yell abuse
Kirobaito - "I wub you KB" "Kiss me Casey" (At the time of writing, he STILL hasn't received the second one and I sent it like a week ago)
Jack - probably involved salt.
Heath - I said I loved Kuja's pants.

....wow. I'm scary!
