mid-teens crisis 

Refers to the sense of panic that occasionally surfaces in adolescents as a result of the feeling of not having done enough, whether it is regarding their academic or social life. Typically experienced around the ages of 15 to 16. Or, alternatively, could also refer to a feeling of worthlessness experienced around this age, but is not necessarily the result of depression.

Many teenagers experience a mid-teens crisis the summer before the eleventh grade as the reality of high-school graduation and preparation dawns on them.

TennisCock

A person with unlimited capacity to instantaneously transform personality from a mild state of relative benign, cordial normalcy into a seething, unreasonable, highly-argumentative and unreachable social abomination when faced with perceived on-court tennis adversity; most often an attribute of 'hot-blooded' Hispanic, Mexican and South American males, although females and other ethnicities may become inspired under the appropriate destabilizing conditions.

At the last tennis tournament we all just watched and waited for the 'bad call' that would ignite his inner TennisCock...and then it happened.
'DASS eet !!' leaping out of the chair and approaching the ref, 'Say hullo to my leetle frênd'!!
