In preparation for the infiltration, Marvel Comics depicts the two super heroes out of costume and observing from a rooftop a street filled with what can only be described as a Tea Party protest. The scene shows crowds of people in city streets carrying signs that say, “stop the socialists,” “tea bag libs before they tea bag you,” and “no to new taxes.” Naturally, the people in these crowds are depicted as being filled with nothing but white folks.

The black character asks the out of costume Captain, “What the hell is this?” And follows that with, “looks like some kind of anti-tax protest.”

This discussion culminates in The Falcon wondering how a black man would do such a thing. “I don’t exactly see a black man from Harlem fitting in with a bunch of angry white folks,” he tells the incognito Captain America.

The Captain tells him, “no it’s perfect… this all fits right into my plan.” After this we find that the Captain’s plan is to send the black man into a redneck bar to pretend to be a black man working for the IRS and to get everyone all mad… because… well, you know that every white person is a racist that hates black civil servants, right?

Tea Bagging is such a stupid name. At least for political causes.

Well the "Tea Parties" gets the name from the Boston Tea Party. I have not heard them use "Tea Bagging", only Marvel Comics. Tea Bagging is a sexual reference of sorts.
