1. To pop one. When your little
fella pops up to say hello - an erection, usually spontaneous, brought on by a sudden event such as a
hot, barely-dressed
girl walking by.
2. Similar to the above but used in figurative speech to imply an extreme liking for something.
1. We were at the
beach last week and Maria took her top off, I was
popping one so bad I had to go sit down in the
shade.
2. I was totally popping one when I saw The Fucking Champs live.
