I Became My Colleague's Mobile Toilet
The situation you described, 'I became my colleague's mobile toilet,' is not a common occurrence in reality. Based on related descriptions of 'I became a mobile toilet,' it is speculated that it may be an exaggerated and absurd scenario used to express certain困扰 (troubles). Here are some possible perspectives for analysis:

An Exaggerated Expression of Workplace Interpersonal Troubles
In the workplace, if the relationship with colleagues is not harmonious, one may encounter unreasonable treatment. For example, colleagues may constantly boss you around, asking you to do various trivial and unreasonable tasks, treating you as a freely usable 'tool.' In this case, using the exaggerated phrase 'became my colleague's mobile toilet' may be to emphasize being overused by colleagues, not receiving due respect, and feeling extremely wronged and dissatisfied inside. This expression is a venting of emotions, highlighting one's unfavorable situation through an absurd metaphor.
A Metaphor for Excessive Work Burden
When the workload is heavy, not only do you have to complete your own job duties, but you also have to continuously take on additional tasks pushed by colleagues, just like a 'mobile toilet' constantly receiving various 'excreta' (here, a metaphor for work tasks). This excessive work burden makes one feel immense pressure and physical and mental exhaustion, as if one has become a 'container' specifically for solving colleagues' work problems, losing control over oneself and time for rest.
Suggestions for Coping
If you are truly facing similar troubles, first clarify your bottom line and principles, and bravely refuse unreasonable requests. You can have an honest conversation with your colleagues, expressing your feelings and thoughts to let them understand your situation. At the same time, you can also report the situation to your superiors and seek reasonable solutions to safeguard your legitimate rights and interests and maintain a good workplace environment.
