The act of turning a penis numbing condom inside out, applying the condom on the penis, and then having your significant other unknowingly give you a blowjob in turn numbing their mouth like novocaine.
She was whining about her toothache all night so I did the noble thing and gave her some blowvocaine.

After some blowvocaine, my girlfriend was having some trouble drinking from a straw.
