Um girls, now do we really like the word fingering? It's kinda awkward to say. HOKAY SO, vassage is when a finger is introduced to the vagina canal.
"Hey Sue, what did you do with Randy last night?"
"Well we kissed for a while then did something unexpectedly!"
"WHAT? NO WAY. What did he do?"
"He gave me a vassage (vah-sawg)."
