It means constantly sweaty hands(yeah, even now). I had 2 dates with this girl and I only touched her once - when we shook hands. It's just really hard to flirt with this ****ty condition. For example when she crouched to fix her laces I would have offered her a hand to stand up, but I couldn't and felt bad because I believe she wanted me to do that. Or when I felt like kissing her, I didn't want to touch her face with sweaty hands, etc...
Stuttering on the other hand is a really cute condition, although only by girls.
