This isn't actually what she's saying. In the episode she can't find a rhyme for "Rachel" or "Chandler". So she just slurs her lyrics and says "andler" at the end of the line to make it rhyme with "Chandler".

The subtitles don't reflect what was written in the script or what she actually said. They reflect what the subtitle transcriptionist heard. If you watch enough shows or movies with subtitles, you'll catch frequent mistakes in the subtitles.

In fact, the first word of this line isn't even "has", it's "have". The entire song is wishing different things for her friends, except Ross, who is instead greeted by Santa Claus despite being Jewish.
