The act of mixing the (vagina) and the (doodle) together in sexual intercourse. The two become one and are then known as vajoodle or having vajoodle.
-"Dee we can hav vajoodle tommorow wen i come over, like all best friends do"
-"Yer, ok i guess all best firends do the vajoodle"
-"i don't want to do vajoodle with Timmy but, i'll have vajoodle with u justcause we're getting married at maccas and all."
This was a phone call between me and my best mate/ex-girlfriend.
