wegschmeißen vs verpassen
to miss / to give
'verpassen' and 'wegschmeißen' can both have to do with an unused opportunity. You use 'verpassen' when you do not take an opportunity, often because you are too late or were not there. 'wegschmeißen' is more colloquial and sounds stronger: you had the chance, but used it badly or gave it up carelessly. The words can be confused because both ultimately mean that a possibility has been lost. 'verpassen' fits better with time and opportunities, while 'wegschmeißen' fits better with waste caused by one's own behavior.
wegschmeißen
Mit dieser schlechten Vorbereitung hat sie ihre Chance auf den Job weggeschmissen.

verpassen
