Verb used to describe stress and annoyance, but specifically caused by an ex of some description, - either ex boy or girlfriend, husband/wife, civil partner. Essentially same definition as "stress" but when referred to it saves the audience from asking WHO the problem is!!

When you eat dirt for the first time and leave your family to build a shack in the woods

when one lad is so fucking tamping(vexed) and stressed at the same time.
