I really do hate the term "Fat Tuesday" I prefer Shrove Tuesday, but hey that is just me.
In case you don't know the meaning of the word "shrove:" it is the past tense from the verb " to shrive."
Now shrive is an interesting word: it is both objective and subjective,; it means both to make confession and receive penance and accept absolution and also to hear confessions and give penance and grant absolution
Confession, penance, absolution.
The Confessor shrives and the Penitent is shriven.
Feel free to glean what you will from this short treatment of the word
Scripture to keep in mind
Six things there are, which the Lord hateth, and the seventh his soul detesteth:  Haughty eyes, a lying tongue, hands that shed innocent blood,  A heart that deviseth wicked plots, feet that are swift to run into mischief, A deceitful witness that uttereth lies, and him that soweth discord among brethren.  My son, keep the commandments of thy father, and forsake not the law of thy mother. ***Cf:Douay-Rheims Proverbs 6: 16-20
