Manically

The dog manically barked at the mailman, startling him.

He laughed manically, making everyone around him uncomfortable.

He cleaned the house manically, as if preparing for a visit from royalty.

He manically cheered for his favorite team, waving a giant foam finger in the air.

He manically screamed at his boss, leading to his dismissal from the job.

He manically checked his phone every five minutes, waiting for a response from his crush.

She was manically cleaning her house for the arrival of guests.
