"Suck it up and deal" is a common silencing response to complaints of sexism.
Example[]
"Bob" asks "Alice" for an example of why female students may feel unwelcome in computer science classrooms, and Alice says, "Suppose you walk into a classroom and the first thing you hear is the lecturer saying 'we need to make our systems so usable that even your mom could use them'; would you feel more or less welcome?" It's common for Bob to respond that he wouldn't feel unwelcome in such a situation if he were a woman, because he would just suck it up and deal; after all, Bob would say, computer scientists frequently use "so easy your mom could use it" as a benchmark, and anyway, why would he let that stop him from being interested in computer science?
Analysis[]
'Suck it up and deal' and its variations deconstruct as a combination of blaming the victim for their feelings, implied denial of experience, implied demand of personal endurance against a system of oppression, explicit expression of no compassion nor interest, and explicit demand for the person to be silenced.
As a rhetorical device, "Suck it up and deal" serves as a double bind: if you fail to give examples of sexist comments or behavior, you're accused of inventing a problem. If you do give examples, almost any example can be dismissed as something women would be able to deal with if they weren't oversensitive / overemotional / not really interested in technology anyway.
"Suck it up and deal" is also a convenient way of disregarding the emotional labor required to, in fact, suck it up and deal (something almost any woman in a technical career already does frequently just to get through the day), the toll that such labor takes on a person over time, and the energy it drains that could otherwise go into work. Like the Male experience trump card, "Suck it up and deal" is a way for people who have never had sexist comments aimed at them to deny the reality that such comments have an effect.
