A breast cancer charity refunded a $7,000 donation to a group of YouTube pranksters after they learned the money was raised through the “motorboating” of female strangers, the Internet group said Monday.

“We got an email from the original charity we donate to saying they appreciate the effort but have to refund the donation,” said one of the members of the group, Kong, in a video posted online.

The pranksters’ group, Simple Pickup, created a viral video last week in which they told random women their group would donate $20 to a cancer charity if the women would allow them to “motorboat” their breasts.

“Motorboating” is the act of pushing one’s face in between a women’s breasts and rocking one’s head side to side.

The video was met with some controversy and a staff writer at the Internet news publication The Daily Dot alerted the Breast Cancer Research Foundation as to how the money was raised.

“Thank you so much for bringing this to our attention,” spokeswoman Peg Mastrianni told The Daily Dot. “We appreciate efforts to raise money to advance breast cancer research, but out of respect for the community we serve, we have asked SimplePickup to cease all references and associations to our organization and are refunding their donation immediately.”

A spokesperson for the Breast Cancer Research Foundation echoed this sentiment to TheBlaze on Tuesday.

“At the end of the day we sometimes have to be sensitive to the community we serve. So while we appreciate their intentions they raise money we just had to refund this particular donation,” the spokeswoman said.

In the Simple Pickup’s video posted Monday, the group lashes out at “haters” who pressured the charity to return the money.

“It’s obvious that they had to do this because they were getting pressured by a small minority of haters who thought that this video was offensive,” said Kong. “Congratulations haters, breast cancers research literally just lost $7,000.”
