A vagina thats small and easy to handle.
I just bought a small, compact car with easy handling. It's exactly like your girlfriends vagerbil!
(v.) To insert a gerbil into a vagina.
I went to a sex show in Scandinavia and this chick totally vagerbilled in front of everybody. I wanted to look away, but a vagerbil is like a train wreck... you just can't stop watching.
