It's still 4/4 time, but the rhythm performed is called a hemiola, meaning three notes in the time normally assigned to two. Notated, it would look something like this:

X: 1
T: Hemiola
M: 4/4
K: none
L: 1/4
(3BBB (3BBB |
w: don't want to x x x

Each group of three quarter-notes lasts two beats. Put another way, each quarter-note lasts 2/3 of a beat.

UPDATE: There are two uses of "hemiola". The looser usage, as above, is for three notes placed in the time of two. However, the stricter definition requires that the 3:2 relationship occur by regrouping the basic pulses, which is not the case here. See the comments below as well as Just how specific is the term “hemiola”?.
