On as informal "we"
"On" is commonly used in spoken French to mean "we"; it takes singular verb agreement but can be plural in meaning.
Reflexive passé composé with être
The verb "s'amuser" uses être as its auxiliary; the past participle agrees with the subject when the reflexive pronoun is a direct object.
Past participle agreement
With "on", the past participle is usually masculine singular (amusé), but many speakers add a plural "-s" (amusés) when "on" clearly refers to a group.
Adverb order
"Vraiment" (really) intensifies the following adverb "bien"; the typical order is très/bien + adjective/adverb, but with "vraiment" it precedes.

Comment était la soirée hier?
How was the party last night?
On s'est vraiment bien amusé.
We really had a lot of fun.
✕Common Mistakes
Nous nous sommes vraiment bien amusés.
Using "nous" sounds overly formal; native speakers prefer "on" in casual speech.
On s'est bien vraiment amusé.
Placing "bien" before "vraiment" changes the emphasis and sounds unnatural.
On se vraiment bien amusé.
The reflexive pronoun must match the subject; "s'est" is correct for "on", not "se" alone.
On s'est vraiment bien amusé.
If you want to stress the plural group, add the "-s": "amusés"; leaving it singular is also acceptable but many learners forget the optional agreement.

Cultural Tip
In everyday French, "on" replaces "nous" in most spoken contexts, especially among younger speakers. The reflexive verb "s'amuser" is the go‑to way to talk about having fun, and adding "vraiment" adds emphasis. Be aware that the past participle can stay singular (amusé) or take a plural "-s" (amusés) depending on how formal you want to sound; both are accepted in conversation.
