Tubthumping is going out and singing and having drinks after protesting.

Song by chumbawamba:
I get knocked down, but I get up again...
Tubthumping was something the Irish did when they were revolting against England. The word was made popular recently by the Anarchist band Chumbawamba, with their song by that title.

He drinks a whisky drink
He drinks a vodka drink
He drinks a lager drink
He drinks a cider drink

Song by Chumbawamba, which makes you feel like pissing the night away and singing when your winning...
I get knocked down, but I get up again
You're never going to keep me down!

Paul and I tubthumped for 2 hours straight. We bent the tub and my ass will never be the same again.

when one consistently gets knocked down, but back up again in a metaphorical manner.
It was a hard day at work, and I have been tubthumping the whole time.

Exhibiting extreme tenacity beyond one's normal stamina. Taken from the song "Tubthumping" by Chumbawamba.
The boxer was tubthumping by the third round, and ended up beating his less-tenacious opponent.
