There was a time when my friends and I would chant this at the slightest provocation:
Anhaal nathrak Uth vos bethod Dothial tienvay!
I've come to find that this line was constructed from Old Irish:
In Old Irish:
Anál nathrach, orth’ bháis’s bethad, do chél dénmha
In Modern Irish:
Anáil nathrach, ortha bháis is beatha, do chéal déanaimh
Serpent's breath, charm of death and life, thy omen of making.
