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

'some ladies kiss sloppily' is the definition.
I can't tell whether this definition defines the answer.

'some ladies kiss sloppily' is the wordplay.
'some' says to take the initial letters.
'kiss sloppily' becomes 'ax' (I can't explain this - if you can you should give a lot more credence to this answer).
The first letter of 'ladies' is 'l'.
'l'+'ax'='LAX'

Can you help me to learn more?
