A guy who seems sweet and kind because he flirts and gives you unwarranted attention, but who is actually a creepy predator/pervert on the prowl for some new (usually young) girl of whom he can take advantage. A groundhog spends the majority of their time being an underground gets labeled as such because of the amount of time they remain underground sleezes. The best defense against groundhogs is to chase them out of their holes and expose them.

The point of having to poop so bad that it starts peeking out of your butthole, like a groundhog peeking out if it's hole, and you have to squeeze it back in to hold it until you get the restroom.

A sexual act: Two partners stand back-to-back with asses touching. One of the people (usually the man) will then shit into the other person's ass (or into a girl's vagina). This is sometimes used for librication. Usually people do not continue shitting in the person's ass (or vagina) until they have an orgasm (although if it's "kinda hard" you could use it as an immitaion dildo), since that would take a lot of shit. It is usually just done as something to try. Named as a joke from the movie "Rat Race" when a woman had to shit and "it was poking out a little pit...like a groundhog". Also sometimes referd to as a gopher.

Whenever feces slowly emerges from your anus after trying to hold it in for too long, similar to the head of a groundhog peeking out from its burrow.

Watching the movie Groundhog Day (1993) starring Bill Murray on repeat on Groundhog Day, thus maximizing the number of times the main character, Phil, lives the same day over and over, and creating one's own Groundhog Day experience. Festivities also include shoving a whole slice of cake into one's mouth and saying the word "doozie" much like the character Ned Ryerson.
While groundhogging yesterday my friends and I watched the movie more than five times and ate more than two cakes. Groundhog Day is my favorite holiday.
