Trib writers Rick Pearson and Monique Garcia having fun in story about Gov. Quinn and pension reform:

Back in the 1970s, Quinn was a populist organizer known for launching petition drives to cut the size of the Legislature and starting tea-bag protests over legislative pay.

And:

Perhaps in an era of tea party politics helping to drive Republicans in the national debate over the size and cost of government, the Democratic governor and his tea-bag protests may be back in vogue after all.

Urban dictionary definitions?

Tea bag:

(v). To lower your body as to dip the testicles into her mouth as the woman is tonguing the scrotum.

(n. or v.) To place testicles in someone’s mouth and proceed in a up and down motion.

Placing your testes inside someones mouth and raising and lowering them to look like you are making tea.

I proceded to tea bag the homeless man.
