Lance widened his stance, one hand on his hip and the other outstretched, pointing forward. His steely gaze signaled unwavering resolve. "Right now," he ordered, his voice carrying an authoritative edge. Instinctively, he flexed his triceps, the muscles firming as he prepared for the task at hand.

To convey a sense of immediate urgency that is even more intense than saying "right now," you might add temporal emphasis or an ultimatum. Here are a few examples: 1. "This instant!" 2. "Without another second's delay!" 3. "Immediately, if not sooner!" 4. "At once!" 5. "Do it before you draw another breath!" In the context of the scene you described, you might rephrase it like this: Lance widened his stance, one hand on his hip and the other outstretched, pointing forward, his steely gaze signaling unwavering resolve. "This instant," he commanded with a tone that brooked no argument, and then instinctively flexed his triceps, ready for immediate action.

For an iconic and dramatic command that suggests the ultimate level of intensity and urgency, consider the following option that echoes the drama of classic movie lines: Lance widened his stance, one hand on his hip and the other outstretched, pointing with a commanding presence. His eyes mirrored the steel resolve of a seasoned leader. With a voice that cut through the air like a blade, he thundered, "Yesterday!" The word reverberated with the weight of immediacy, underscoring the gravity of the situation. As though his body responded to the severity of his own command, he instinctively flexed his triceps, muscles tensing in anticipation of the looming challenge.

Lance adopted a broad stance, an authoritative hand on his hip and the other extended confidently--finger pointed unwaveringly towards an unseen horizon. His eyes, fierce with determination, locked onto the task ahead. "Not tomorrow, not in an hour--now!" he thundered with a gravity that seemed to halt time itself. His command was a call to arms, his presence the embodiment of action. As the words left his lips, a visceral tension coursed through his triceps, each muscle fiber standing to attention like soldiers awaiting their captain's next order.

Lance steadied his stance, hand on hip, the other arm outstretched, finger aimed like a missile. "Not tomorrow, now!" he barked, a command that made the air quiver. His triceps rippled into action, every sinew ready to strike.

Lance grounded himself, feet apart, hand on hip, the other pointing with fierce intent. "Now! Immediately!" he commanded, his tone brooking no delay. Triceps tensed in readiness, his entire form screamed urgency.

It sounds like you're looking to portray a bit of verbal sparring with a barbed, sarcastic retort. If you're aiming for a character to return a biting comeback to someone who just insulted them for being unfriendly or unpopular, here's an example of how they might respond: "Better to be remembered for a sharp tongue than forgotten for a dull personality. Quality over quantity, right?"
