Calling someone a 'pap', 'papsmear', 'papsmearian' or 'smear' is one of the worstpossibleinsults. It describes them as the by-product of woman's annual 'papsmear'.
"I can't believe you'd do that! You're a 'papsmearian'!"
"Look at that pap across the street."
"Hey papsmear, pass the bong."
"Hey pap! Stop smearing it! Don't smear you 'papsmearian'."
One of the few acceptable anywords still left in existence, it takes its root from a euphemism for passing wind, however it has since grown into popular usage as a less offensive, more playful version of crap.
"That is utter pap!"
"What a pappin' ho that Sheila is..."
"I'd like to teach him a thing or two about papping..."
