power-pram
v.— «Seriously, every Saturday on 24th Street it’s like a fucking baby fair—double strollers even, toddlers wearing outfits that cost more than one of my paychecks, mothers power-pramming, as they say in England, combining exercise with pushing a baby stroller (sounds like a good idea, looks disgusting and a bit cruel) and a general sea of proud reproducing parental faces smiling and happy and just itching to talk childbirth, pre-school waiting lists and infant movement classes or yoga for children. » —“Babies, Roommates and Tricks in Noe Valley” by Don Baird Bay Times (San Francisco, California) Apr. 17, 2008.

This looks like a verb to me.
You’re right—it’s best given in the infinitive form.
