Stuck-up It Girl's first touching gesture (3)

I believe the answer is:

tig

I'm a little stuck... Click here to teach me more about this clue!

'touching gesture' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'stuck-up it girl's' is the wordplay.
'stuck up' says the letters should be written backwards.
'girl' becomes 'g'.
'it' in reverse letter order is 'ti'.
'ti'+'g'='TIG'

'first' acts as a link.

Can you help me to learn more?
