Alex Rodriguez - variation of his common nick of "ARod". Most likely coined when his usage of lip balm looked a lot like lipstick. Came into wide usage (outside of NY) after his illegal swipe at the pitcher in Game 6 of the 2004 ALCS.
Please Ignore My F***up. As in SNAFU, the (F) is reader assigned. Posting in blog comments or non-editable forums, sometimes perfectionists (or just anal people) will add a post correcting a typo that slipped through preveously, then add PIMF.
