sneaked
Went without detection
Sneaked is the past tense and past participle of sneak—to move quietly and furtively: She sneaked out after midnight.
Snuck has become an increasingly common alternative, especially in American English, though some regard it as nonstandard.
Both forms are widely used: He sneaked/snuck a cookie from the jar.
