No, it's not what lioor calls his accomplishments after drinking too much on Christmas Eve. It's a real holiday tradition.

Tió de Nadal ("Christmas Log"), or more properly known as the "Caga tió" ("pooping log"), is a character in Catalan mythology relating to a Christmas tradition widespread in the Catalonia region of Spain.

From the wiki page:

"Beginning with the Feast of the Immaculate Conception (December 8), one gives the tió a little bit to "eat" every night and usually covers him with a little blanket so that he will not be cold at night.

On Christmas day...one puts the tió partly into the fireplace and orders it to "poop". To make him "poop", one beats him with sticks, while singing various songs of Tió de Nadal."  

One of those songs, roughly translated, goes a little like this:

Poop log,
Log of Christmas,
Don't poop herrings,
Which are too salty,
Poop turrón
Which is much better!

Log, log,
Giving log,
Don't give us herrings,
They are too salty,
Give us treats,
Give us sweets!
