Twault

1) A failed attempt to insert a penis into a vagina (or twat). In other words: the "serve" falls outside the "service box". Twault=(Twat+Fault)-See "Fault" in regards to tennis. 2) When a male's erect penis gets caught on the vaginal surface (usually upon a failed insertion attempt or correcting for slipping out during intercourse) causing a pole vaulting type of phenomenon that the male would endure. 3) Twault=Twat+Vault (e.g., a bank vault. Only instead of a bank, it's a twat.): When a woman withholds the release of sex to her partner, much like Disney does with its movies. The sex is then said to be "locked in the twault". See Disney Vault for clarification.
