だろ

だろ is the casual, truncated form of だろう. It carries a confident, assertive tone — the speaker expects the listener to agree. Unlike だよな, which invites shared agreement, だろ pushes the speaker's view.

Register

だろ can sound pushy or confrontational depending on context and intonation. Used among close friends, it is natural. Used with strangers or superiors, it can come across as rude.

• だろ: casual masculine
• だろう: slightly more formal
• でしょ: casual, gender-neutral to feminine
• でしょう: polite

だろ is strongly masculine. Women typically use でしょ or でしょう in the same situations, which carries the same meaning with a softer tone.
