Rather funny question. If you are asking whether 'Thip' is a common real name then the answer is absolutely NOT.

You have mis-understood that Thip is not a real name but instead a nickname.

Any Thais that call their daughter Thip must have been too lazy to think up a decent name.
Thais 'usually' have one syllable nicknames as in Thai language the nickname is often used in speech to replace the pronoun 'I'.

'Thip' is a very common nickname, however its getting a little old-fashioned in the big cities.
