Sudden attack

[Vania]

A [sudden attack] is a sudden, unexpected, unstoppable need to take a massive dump. Most often occurs in those with [Irritable Bowel Syndrome] or those who just consumed a large amount of fast food. 95% of the time, a sudden attack doesnt leave you enough time to walk to the nearest crapper forcing you to sprint like a madman which only makes it harder to hold it in. As such, youre forced to clench your [asscheeks] together as hard as you can resulting in a very awkward looking running posture that is certain to catch the attention and imagination of all nearby.
