Rioting
as it is used here, means,


...To run to excess in feasting, drinking, or other sensual indulgences.


Webster's 1828
The night is far spent, the day is at hand:
let us therefore cast off the works of darkness,
and let us put on the armour of light.
Let us walk honestly, as in the day;
not in rioting and drunkenness,
not in chambering and wantonness,
not in strife and envying.
But put ye on the Lord Jesus Christ,
and make not provision for the flesh,
to fulfill the lusts thereof.

Romans 13:12-14
