(CNN) – Former Sen. Scott Brown said he wasn't drunk when he tweeted this: "Bqhatevwr."
The Massachusetts Republican, who was ousted from his seat in November, sparked a round of questions on Twitter last month after posting multiple late-night tweets, including one that seemed to come from some fumbling thumbs.
When asked about that "tweeting thing" by a reporter with the Boston television station, Fox 25, Brown responded: "Anyone ever hear of pocket tweet, pocket dial? I mean it was pretty simple."
"I mean, I have an iPhone 5," he continued, pulling his phone out of his pocket. "If anyone has iPhone 5, the keys are small. It's very, very sensitive."
The bizarre word came amid a series of other unusual tweets responding to critics–and they all had one word in common: "whatever." They have since been deleted.
"@mattinsmrvlle whatever," read one tweet.
Then another: "@BudParsons whatever bud"
Next: "@Erudite_Enigma whatever michael"
Then came the now-infamous garbled term–"Bquatevwr"–which, in the days of rapid catch phrases, quickly became a trending hash tag on Twitter.
He continued to tweet, saying again "whatever" before adding in the another tweet: "Your brilliant Matt."
While the tweets no longer appear on his page, the comments were captured by screen shots online.
The incident came before Brown announced that he would not seek the Senate seat vacated by Democratic Sen. John Kerry, so Brown's name was still buzzing in the Massachusetts political world at the time. He now says he’s considering a run for governor in 2014.
While the tweets fueled speculation that the former senator was drunk tweeting or his account had perhaps been hacked, Brown said it was simply an accident.
His daughter, he said, was teaching him how to use Facebook and Twitter on his phone.
"We were here in the living room and responded to a couple of people and then put it in my pocket," he said in the interview. He added he woke up the next morning and realized it had become a big story.
Asked if it was a really was just a mistake, he said "what else would it be?
"I rarely drink. The last time I was ever drunk was my bachelor party," he added. "I guess no one has ever pocket dialed or pocket tweeted before."
